For every $20 Mike earns, he puts $4 into savings. Mike is going to graph his savings. The x-axis will be the amount earned, and the y-axis will be the money saved. What will be the slope of Mike's graphed line?
We know that every time Mike earns $20 he will deposit $4 into his savings account. We know that the equation for slope is Rise / Run. Because the Y-axis represents the amount Mike has earned we can go ahead and put 20 for the Rise. Since the X-axis represents the amount Mike has saved, we can set the Run equal to 4. To find slope just divide
20 / 4 = 5
The slope equals 5/1
