Question 504494: "Passes through the points (7,8) and (-2,3). Be exact please, no decimals. you can skip the graph on this one."
I found the slope by doing: %28y2-y1%29%2F%28x2-x1%29=m %283-8%29%2F%28-2-7%29=5%2F9. If the formula was y=mx%2Bb I need help finding b please. Now I go 3=%285%2F9%29%28-2%29%2Bb but i don't know what to do.

You're on a good start. Solve for b by multiplying 5/9 by -2, then by subtracting that from both sides.
