Question 218162: y=200+15m
y=100+20m at what point do they intersect?
Answer by nerdybill(7384) (Show Source): You can put this solution on YOUR website!
y=200+15m
y=100+20m
.
Set them equal to each other and solve for m:
200+15m=100+20m
200=100+5m
100=5m
20 = m
.
Plug the above into either equation to find y:
y=200+15m
y=200+15(20)
y=200+300
y=100
.
They intersect at (m,y)=(20,100)
