First I chose two points on the line that fall on 2 intervals or 2 lines. Then if found the slope of the two points. Using the slope and one of the points I pugged the numbers into an equation to solve for b. Once I found b I wrote an equation using b and the slope. y=-2/3+300 steps: (250,200)(300,100) 100-200/300-150 -100/150 or -2/3 100=-2/3(300)+b 100=-200+b 300=b y=-2/3b+300
