First you need to figure out the slope:
y2-y1/x2-x1=(1+5)/(-5-7)=-1/2
y+5=-1/2(x-7)
y=-1/2x-3/2

Answer:
Total 25.45 hours will be taken to empty the pool.

Amount of pool emptied by large pumpkin in one hour=
Amount of pool emptied by small pumpkin in one hour=
Amount of pool emptied in one hour if both pumpkins work together=
+ 
=

Total 25.45 hours will be taken to empty the pool.
If feet:
34' 4" - 8' = 26' 4"
if inches: = 33' 8"
608
607.5
.5 rounds up to 1
