ANSWER:
y = 3/4x + 10
STEP-BY-STEP:
I will write the equation in the slope-intercept form: y = mx + b
y = y-coordinate
m = slope
x = x-coordinate
b = y-intercept
Part 1: Substitute the knowns into the equation
y = mx + b
4 = (3/4)(-8) + b
1. Simplify
4 = -6 + b
Part 2: Solve for b
1. add 6 to both sides to get b by itself on one side
4 + 6 = b - 6 + 6
2. Simplify
10 = b
Part 3: Re-write equation with 3/4 substituted in for m and 10 substituted in for b
y = 3/4x + 10
