Me solve this 7th grade math problem, you!

The correct answer is s = 27.

Step-by-step explanation:

This problem already gives us an equation so all we need to do is plug in the numbers:

c = 39.95 + 0.15(s + r) becomes 53.45 = 39.95 + 0.15(s + 63). Now to solve:

53.45 = 39.95 + 0.15(s + 63)

13.50 = 0.15(s + 63)                     Subtract 39.95 from both sides

13.50 = 0.15s + 9.45                    Distribute 0.15 to s and 63

4.05 = 0.15s                                 Subtract 9.45 from both sides

27 = s                                           Divide both sides by 0.15

Hope this helps,

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
