What is the slope of the graph? a) 15 b) 10 c) 1.5 d) 1 i know c and d are definitely wrong.

I would go with B) 10 because if you look it intercepts the y at 15 and in 1 square it goes up to 25 and so forth which is a 10/1 slope
So in the future use the formula y2-y1/x2-x1. Pick two point usually you want point that fall on a grid line but work with what you have so 45-35 / 3-2 = 10/1

Your answer will be
