A. 20x + 10y = 500
...
B. 10y = -20x + 500
y =
y = -2x + 50
y intercept is 50
x intercept is where y = 0
0 =-2x+50
-50=-2x
x = 25
x intercept is 25
...
C. The intercepts indicate how many hours must be worked on one job without working any hours on the other job.
y intercept of 50 means, 50 hours of y, washing windows, with 0 hours of mowing.
x intercept of 25 means, 25 hours of x, mowing, with 0 hours of washing windows
...
D.
...
E. If y = 30, then x = ?
30 = -2x+50
2x = 50-30
2x = 20
x = 10 hours mowing
