Explanation:
Y intercept is 500 because she is starting off with $500 each month
slope is 75 because she gets $75 more every time she sells one
start at (0,500) then plot a point at (1,575) then (2,650) increasing by 75 every time x increases by 1
If you start at (0,500) you can move backwards going to (-1,425) to (-2,350) decreasing by 75 as you move backwards
the equation is y=75x+500
table: -3 275
-2 350
-1 425
0 500
1 575
2 650
3 725
4 800
