1. y2-y1 divided by x2-x1 which would be y2-y1/x2-x1
2. plug in : -2-19/3-(-6)
4. Solution ( -7.3 or -2.3 )
Answer:
[tex]y = -\dfrac{7}{3}x +5[/tex]
Step-by-step explanation:
The general equation of a line in slope-intercept form is
y = mx + b
where m = slope and b = y-intercept is rise over run
[tex]m = \dfrac {(y_{2} - y_{1})} {(x_{2} - x_{1})}[/tex]
where (x₁, y₁) and (x₂, y₂) are any two points on the line
For the line passing through (-6, 19) and (3, -2) , the slope
[tex]m = \dfrac{-2 - 19}{3 - (-6)}\\\\[/tex]
[tex]\\\\m= \dfrac{-21}{9}[/tex]
[tex]m = -\dfrac{7}{3}[/tex]
So slope-intercept form is
[tex]y = -\dfrac{7}{3}x +b\\\\[/tex]
To compute y-intercept, b, plug in any of the two points into the above equation and solve for b
Let's choose point (3, -2)
Plugging x = 3 and y = -2 gives
[tex]-2 = -\dfrac{7}{3}\cdot 3 +b\\\\\\\\-2 = -7 + b\\\\[/tex]
So equation of line is
[tex]y = -\dfrac{7}{3}x +5[/tex]

Help me please I'll give brainliest to the most helpful answer or the answer that makes the most sense.
Answer:
x = 120°
Step-by-step explanation:
Since s and t are parallel and are on a supplementary line, that means that the interior angle and the exterior angle (60°) will equal 180° (supplementary)
So to find the angle of x, you have to minus 60 from 180, and you get x, which is 120°

Find the other endpoint for the midsegment of the given trapezoid.
Applying the midpoint formula, the endpoints for the midsegment are (-0.5, 0.5) and (-5/2, -7/2).
What is a Midsegment of a Trapezoid?The midsegment of a trapezoid is the line segment that intersects the two legs of the trapezoid at their midpoints.
Hence, to find the endpoint for the midsegment of the other leg of the trapezoid, apply the midpoint formula, M[(x2 + x1)/2, (y2 + y1)/2].
Find the midpoint between A(-2, -5) and B(-3, -2):
A(-2, -5) = (x1, y1)
B(-3, -2) = (x2, y2)
Plug in the values
M[(-3 + (-2))/2, (-2 + (-5))/2]
M(-5/2, -7/2)
Therefore, using the midpoint formula, the endpoints for the midsegment are (-0.5, 0.5) and (-5/2, -7/2).

The frequency of the red light is 4.6 × 10⁵ Hz
Calculating frequencyFrom the question, we are to determine the frequency of the red light with the given wavelength
From the given information,
Wavelength = 650 nm
c = 3.0 × 10⁸ m/s
From the formula,
c = fλ
∴ f = c/λ
Where c is the speed of light
f is the frequency
λ is the wavelength
Thus,
f = 3.0 × 10⁸/650
f = 4.6 × 10⁵ Hz

Step-by-step explanation:
What is the slope-intercept equation of a line that goes through
(8,5) and (7,4)?
Write the equation in standard form of a line that goes through
(-15,2)is perpendicular to a line has a slope of-5.
What is the point slope equation of a line that goes through
(-2,-7) and is parallel to y=14x-3?
If y and x vary directly and y=1.4when x=3.2, what is x when y=2.6? Round to two decimal places.
1. The slope-intercept equation of the line is: y = x - 3.
2. The equation of the line in standard form is: -1/5x + y = 5
3. The equation in point-slope form is: y + 7 = 14(x + 2)
4. The value of x ≈ 5.94
How to Find the Slope?Slope (m) = y2 - y1/x2 - x1.
There are three ways too write the equation of a line, they include:
As slope-intercept form, y = mx + bAs point-slope form, y - b = m(x - a)As standard form, Ax + By = C.1. find the slope (m) of the line that passes through (8, 5) and (7, 4):
Slope (m) = (5 - 4)/(8 - 7)
Slope (m) = 1/1
Slope (m) = 1
Substitute m = 1 and (a, b) = (8, 5) into y - b = m(x - a):
y - 5 = 1(x - 8)
y - 5 = x - 8
y = x - 8 + 5
y = x - 3
The slope-intercept equation is: y = x - 3.
2. The slope of perpendicular lines are negative reciprocals, therefore, the slope of the line perpendicular to the line that has a slope of -5 would be, m = 1/5.
Substitute m = 1/5 and (a, b) = (-15, 2) into y - b = m(x - a):
y - 2 = 1/5(x - (-15))
y - 2 = 1/5(x + 15)
y - 2 = 1/5x + 3
y = 1/5x + 3 + 2
y = 1/5x + 5
-1/5x + y = 5 [standard form]
3. Parallel lines have the same slope. The slope of y = 14x - 3 is 14. The line that is parallel to y = 14x -3 would also be, m = 14.
Substitute m = 14 and (a, b) = (-2, -7) into y - b = m(x - a):
y - (-7) = 14(x - (-2))
y + 7 = 14(x + 2) [point-slope equation]
4. y = kx
1.4 = k3.2
1.4/3.2 = k
The equation would be: y = 1.4/3.2x
Substitute y = 2.6 to find x:
2.6 = 1.4/3.2x
(2.6)(3.2) = 1.4x
8.32 = 1.4x
8.32/1.4 = x
5.94 ≈ x

Based on the alternate exterior angles theorem, the equation is: 15x - 3 = 14x + 2
The value of x = 5.
What is the Alternate Exterior Angles Theorem?The angles, (15x - 3) and (14x + 2) are alternate exterior angles. Based on the alternate exterior angles theorem/postulate, they are congruent to each other.
Thus, the equation to create in solving for the value of x would be:
15x - 3 = 14x + 2
Subtract 14x from both sides of the equation
15x - 3 - 14x = 14x + 2 - 14x [subtraction property of equality]
x - 3 = 2
Add 3 to both sides

The same honey is sold in two different size jars.
Large Jar 540g for £4.10
Small Jar 360g for £2.81
By considering the amount of honey per penny, work out which jar is the best value for money. Working must be shown.
From unitary method calculations, we have found that the large jar is the best value for money because a penny buys more honey.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
We need to determine which has the best value for money using the quantity a pound can purchase.
So, first for the large jar.
£4.10 will be purchase 540g of honey then,
£1.00 will be purchase xg
Then cross multiplying for x will be;
x = 1.00 (540g )/4.10
x = 131.7g
Hence for the large jar a penny will buy 131.7g of honey.
Now second for the small jar
£2.81 will be purchase 360g of honey then,
£1.00 will purchase xg
Now cross multiplying
x = 1.00 (360g )/ 2.81
x = 128.1g
Hence for the small jar a penny will buy 128.1g of honey.
