Question

I have a question that asks me to look at two pictures that are of signs to warn you of the slope or steepness of the hills, one of those hills increases a short distance and then decreases a greater distance and has 17% written above the line that decreases, and the other one increases a great distance with 30% written above it then it decreases at a much shorter distance. The question I must answer is Sketch hills with each of these slopes. I have two coordinate grids that are blank in wich to draw the hills with there slope. What should they look like and say??
