Here are two points (-3,4),(1,7) What is the slope of the line between them?

Answers

Answer:

3/4

Step-by-step explanation:

The solution is Option B.

The slope of the line between the points P ( -3 , 4 ) and Q ( 1 , 7 ) is 3/4

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first point be P = P ( -3 , 4 )

Let the second point be Q = Q ( 1 , 7 )

Now , the slope of the line between the two points is given by the formula ,

Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 7 - 4 ) / ( 1 - ( -3 ) )

On simplifying the equation , we get

Slope m = 3 / 4

Therefore , value of m is 3/4

Hence , slope of the line is 3/4

The easiest thing to do here is to split into two right triangles. The split will occur at x=1.

A= (base times height) / 2

Height of both is 3
Base of left is 6
Base of right is 3

(6*3)/2 = 9
(3*3)/2 = 4.5

Now, add together.

9 + 4.5 = 13.5 sq units

Use the equation: C=0.5n to determine the cost for 14 hamburgers in dollars

Answers

C=$7.00

C stands for the cost, and n would be the amount of hamburgers. Since we are looking to determine the costs of 14 hamburgers we would have to then multiply 0.5 and 14.

14 x 0.5 =7

So your answer is 7 dollars

14 times 0.5 = 7 would be correct i think.

Hello!

Height of pyramid = 845 feet

Slant height = 856 feet

width = 175 feet

The surface area of a pyramid = The base area of the pyramid added to the area of the 4 triangles.

The volume of a pyramid = 1/3 base area * height

1 Triangle = 1/2 base * height

Triangle = 1/2 * 175 * 856 feet

1 Triangle Area = 74,900 feet

The area of 4 triangles = 299,600 feet

Now, the area of the base = is 175 * 175 feet

Base area = 30,625 feet

Surface area = 30,625 + 299,600 feet = 330,225 feet

Volume = 1/3 * Base area * height of pyramid

Volume = 1/3 * 30,625 feet squared * 845 feet

Volume = 1/3 * 25,878,125 feet cubed

Volume = 8,626,041.(6) feet cubed
