Which graph represents the solution to the given system -2x+5y=-10 and -3x+5y=-20

Find where the x and y intercept

to find x intercept, set  y=0
to find y intercept, set x=0

-2x+5y=-10
xintercept=5
yintercept=-2
1st and 2nd and 4th graph are out

-3x+5y=-20
xintercept=20/3
yintercept=-4

3rd graph out

last graph is answer

B. 2 1/2 feet. multiply 2.5 inches by 12 to get thirty inches then divide by 12 to get 2.5 feet
