estimate the slope of the tangent line to each curve at the given point (3,3)

They also gave you curves (which you did not give us).
"estimate the slope of the tangent line to *****each curve****** at the given point (3,3)"

now that would have been important information to mention. Draw tangent lines on the graphs given at the point (3,3), find slope = (change in y) / (change in x), choose any two points on the *line* (x1,y1), (x2,y2) for the calculations, that is how you estimate. The question requires you understand what a tangent line is, please review your notes and textbook if this is still unclear.
