The slope intercept form is given as y = 2x + 6
The general expression for slope intercept form is given as:
y = mx + c
where, m = slope
c = intercept
The formula for slope intercept form when we have been given the coordinates of a point and slope is given as :
[tex](y-y_{1}) = m(x-x_{1})[/tex] (1)
where ([tex]x_{1} , y_{1})[/tex] = the coordinates of a point
m = slope of the line
putting the required values in equation (1) we get
(y - 4) = 2(x- (-1))
(y - 4) = 2(x+1) [As (-)*(-) = +]
y - 4 = 2x + 2
y = 2x + 2 + 4
y = 2x + 6
Thus the slope intercept form is y = 2x + 6

The temperature in degree Celsius when the temperature is 50°F is; C = 10°C
How to change the subject of the formula?
We are given the formula for converting temperature from degree Celsius to degree Fahrenheit as;
F = ⁹/₅C + 32
Making C the subject;
⁹/₅C = F - 32
Multiply through by 5/9 to get;
C = ⁵/₉F - 32(5/9)
We are told that the temperature is 50°F. Thus;

x² - 12x - 220
After factorization, the factors are (x - 22) (x + 10).
What is factorization?In mathematics, factorization is the process of dividing a large number into smaller numbers that, when multiplied together, yield the original number. Factorization occurs when you divide a number into its factors or divisors. For example, the factorization of the number 12 could be 3 times 4. The Greatest common factor (GCF), the Grouping method, the difference in two squares, and the sum or difference in cubes are the four main types of factoring.So, x² - 12x - 220:
x² - 12x - 220x² - x( 22 - 10 ) - 220x² - 22x + 10x - 220x(x - 22) + 10(x - 22)Factors: (x - 22) (x + 10)Therefore, the factors are (x - 22) (x + 10).

What is an angle on a straight line?
In the field of geometry, and in mathematics, the straight angle is one that is said to be equal to 180 degrees. That is, it is the angle that is called so based on the fact that it appears on a straight line. The sides of the angle are on separate positions compared to that of the vertex that appears also in a straight line.

The cost of purple dye has been increasing over the last few months, and Robyn uses this dye as part of her tie dye scarf business. She’s worried that it will continue to rise to the point where she no longer makes a profit on her scarf sales. She currently has a 20% profit margin ([price - unit costs]/price) and dye is currently 60% of unit costs. What is the lowest percentage increase in the cost of dye that would make Robyn’s scarves unprofitable?
The lowest percentage increase in the cost of dye that would make the scarves unprofitable is 42%
How to calculate the percentage?(Price- Unit Cost)/Price= 20% or 0.2
Price- Unit Cost= 0.2 Price
0.8 Price = Unit Cost
Let Unit Cost be x
Price = x/0.8= 1.25x
Dye is 60% of unit costs= 0.6x
Cost of remaining material= 1 - 0.6x = 0.4x
Unit Cost= Cost of Dye+ Cost of remaining material
So, in order to become unprofitable, Unit Cost must be 1.25x
Therefore
1.25x= Maximum cost of dye+ 0.4x
Maximum Cost of Dye = (1.25-0.4)x = 0.85x
Percentage change in cost of dye= {(0.85x-0.6x)/0.6x}*100= 41.66 or 42%
Therefore, theowest percentage increase in the cost of dye that would make the scarves unprofitable is 42%.

What is the slope intercept form of a line ?
The equation of line that can be written as y = mx + c, where m is the slope and c is the line's y-intercept, is known as a slope intercept form.
1.
It is given that equation is : y = 2/5x - 3.
So , the slope here is 2/5 and a parallel line will have the same slope.
We know that the slope intercept form of a line is :
y = mx + c
Put , slope(m) = 2/5 in above equation.
Given , (1,-1) i.e., x = 1 and y = -1
Now we substitute these values to find value of c.
-1 = 2/5(1) + c
-1 = 2/5 + c
-1 - 2/5 = c
(-5 - 2)/5 = c
-7/5 = c
Putting m = 2/5 and c = -7/5 , we get :
So, the equation of parallel line is :
y = [tex]\frac{2}{5}[/tex] x - [tex]\frac{7}{5}[/tex]
2.
We know that the product of the slope of two perpendicular lines is -1.
Given that equation is : y = -2/5x - 4 i.e., slope = -2/5
So , slope of a line perpendicular to this line is -1/(-2/5) = 5/2
And this line passes through the point (-3,1).
Equation of a line that passes through a point (x1 , y1) and slope (m) is :
(y-y1) = m (x-x1)
Here ;
x1 = -3 , y1 = 1 and m = 5/2
So , the equation of perpendicular line will be :
(y - 1) = [tex]\frac{5}{2}[/tex] (x - (-3))
(y - 1) = [tex]\frac{5}{2}[/tex] (x + 3)
y - 1 = [tex]\frac{5}{2}[/tex] x + [tex]\frac{15}{2}[/tex]
y = [tex]\frac{5}{2}[/tex] x + [tex]\frac{15}{2}[/tex] + 1
y = [tex]\frac{5}{2}[/tex] x + [tex]\frac{13}{2}[/tex]
Therefore , the answers are :
1. The equation of line parallel to y = [tex]\frac{2}{5}[/tex] x - 3 will be y = [tex]\frac{2}{5}[/tex] x - [tex]\frac{7}{5}[/tex] .
2. The equation of line perpendicular to y = - [tex]\frac{2}{5}[/tex] x - 4 will be y = [tex]\frac{5}{2}[/tex] x + [tex]\frac{13}{2}[/tex] .

The unit price of the pair of socks is $7.99
How to calculate the unit price ?
Unit price can be described as the price of one item. In this case scenario, we are looking for the unit price of a pair of socks.
The unit price can be calculated as follows
6 pair=47.94
1 pair = x
Cross multiply both sides
6x= 47.94
Divide both sides by the coefficient of x which is 6
6x/6= 47.94/6
x= 7.99

A package contains 12 resistors, 3 of which are defective. If 4 are selected, find the probability of getting
a) 0 defective resistors
b) 1 defective resistor
c) 3 defective resistors
If a package contains 12 resistors, 3 of which are defective. If 4 are selected, the probability of getting
a) 0 defective resistors: 0.3164
b) 1 defective resistor: 0.4219
c) 3 defective resistor: 0.0469
ProbabilityFirst step is to calculate the probability for a defective resistor and non-defective resistor:
Probability=3/12
Probability =0.25
Non-defective resistor:
Probability=(1-0.25)
Probability=0.75
Now let find the probabilities for defective resistors from 0 to 3
P(0)=1(0.75)^4 ×(0.25)^0
P(0)=0.3164
P(1)=4(0.75)^3× (0.25)^1
P(1)=0.4219
P(2)=6(0.75)^2× (0.25)^2
P(2)=0.2109
P(3)=4(0.75)^0×(0.25)^3
P(3)=0.0469
P(4)=1(0.75)^0 × (0.25)^4
P(4)=0.0039
Hence,
a. P(0)=0.3164
b. P(1)=0.4219
c. P(3)=0.0469
Therefore If a package contains 12 resistors, 3 of which are defective. If 4 are selected, the probability of getting 0 defective resistors: 0.3164, 1 defective resistor: 0.4219, 3 defective resistor: 0.0469.
