18) y = -2x - 1
19) y = -2x
20)
Step-by-step explanation:
With the two points you find the slope using 
Then using that slope, plug the slope in with one of the points values of x and y into the point slope formula, and smiplify that into the y-intercept formula.
The answer would be X=1/2y

Answer:
Step-by-step explanation:
Let her total earnings be m
Rent = 1/4m
Food = 1/5m
Amount left = m - 1/4m - 1/5m
Amount left = (20m - 5m - 4m)/20
Amount left = 11m/20
