What is the slope-intercept equation for the line below? (0,1) (4,3)

y2 - y1

x2 - x1

3 - 1        2            1

= =

4 - 0        4            2

Find the y-intercept:

1 = 1/2(0) + b

1 = 0 + b

-0  -0

1 = b

The slope-intercept equation is:

y = 1/2x + 1

so its D

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
