it's a straight line. Locate point (0,150) on Y axis and point (-6,0) on X axis . Connect these two points with a straight line and you have your graph.

We know this graph cut in Y = 150

Then, we need to find the value of root.

F(x) = 150 +25x

0 = 150 + 25x

25x = - 150

x = -150 / 25

x = -6

I posted the graph here down
