Consider the graph of the function f(x)=-5x^2+3x. Determine the slope of the secant line passing though the two points of the graph when x=1 and x=3. Determine the equation of the line passing through the two points.

I was working on it, to find the slope wouldnt you start with finding the
f '(x) (which from what I understand gives you the slope of the secant line and the slope of the tangent line)?

ok so how do you find the slope of the secant line at those points x=1 and x=3 i guess is where im stuck. I understand at x=1 y=0 and at x=3 y=0. what????

Oh so im making it harder than it really needs to be. So those are the slopes at those points. My last question is what does he mean by Determine the equation of the line passing through the two points.
