Answer:

The answer to your question is -3

Explanation:

Data

A (-8, -35)

B (6, 21)

Process

1.- Calculate the slope

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

x1 = -8 y1 = -35 x2 = 6 y2 = 21

-Substitution

m = (21 + 35) / (6 + 8)

-Simplification

m = 56 / 14

-Result

m = 4

2.- Calculate the equation of the line

y - y1 = m(x - x1)

-Substitution

y + 35 = 4(x + 8)

-Simplification

y + 35 = 4x + 32

y = 4x + 32 - 35

-Result

y = 4x - 3

3.- Find the y-intercept

The y-intercept is the number after the x, for this equation is -3.
