Question 12
 From the given graph, use two points to write an equation in point-
 slope form and then change to slope-intercept form.
 Step 1: Use the two points to find the slope.
 Step 2: Use the slope and one point to complete point-slope form.
 y-y₁ = m(x-x₁)
 Step 3: Change point-slope form into slope intercept form by solving
 for y. Show your work!
 y=mx+b
