Using x and y here. y will be the money you owe him and x is the number of week. y=mx+b, this is the y intercepet form of a linear equation. b is the y intercept of the graph, and m is the slope. Slope represents the rate of change. Since you borrowed 70, your debt will begin at 70 at 0 weeks, which means your y intercept, b is 70. Then you know your debt is decreasing at a rate of 7 dollars per week, which means your slope is -7. So, your equation will be y=-7x+70. Doing some simple math to check, at week 10, your debt is 0, so y=0.
