Slope intercept form is y = mx + b
First step: Pick two coordinates from the graph. I chose: (0, -3) and (-2, 5).
Second step: Now use the formula y2-y1 over x2-x1 to calculate the slope. It should look like this: 5 - - 3 over -2 - 0 = -8/2. Simplify it to -4.
Third step: Write this in slope intercept form.
