Agarbage truck and a dump truck each drive along a straight road between two points. using the points on a map that the city created, the garbage truck will start at (–3, 4) and will stop at (5, 12). the dump truck will start at (5, –3) and will stop at (–4, 33).

what are the coordinates of the intersection that both trucks drive through?

We first find the lines of the motion of each truck, then calculate its intercept.
Garbage truck:
m = (12 - 4) / (5 - 3)
m = 4
4 - y = 4(3 - x)
4x - y = 8

Dump truck:
m = (33 + 3) / (-4 - 5)
m = -4
33 - y = -4(-4 - x)
4x + y = 17

Adding the two equations to solve them, we get:
8x = 25
x = 25 / 8

y = 17 - 4(25/8)
y = 17 - 25/2
y = 9/2

The trucks' point of intersection is (25/8,9/2)

Think of it as five or above give it a shove. change the 5 or above to the right to a zero and add one to the number on the left.
