Question

What is the equation of this line in slope-intercept form?

Answer 1

Slope = (5+3)/(-1-1) = -4
b = y - mx
b = 5 - (-4)(-1)
b = 5 - 4 
b = 1
equation
y = -4x +1

answer
B. y = -4x + 1

Answer 2

When you look ast the graph the line that passes the y-axis will help you determine both the y-intercept and the slope.
The line lands on the y-axis at 1. Now from one, count up 4 spaces and left 1 space. This is what we call rise over run. So your equation would be...
y = 4x + 1.
