**Reiny**, Tuesday, November 16, 2010 at 6:50pmthe slope of the given line is 5

so find dy/dx for the cubic

and set that result equal to 5

you will get a quadratic which factors nicely.

let me know what values of x you got.

**Reiny**, Tuesday, November 16, 2010 at 6:57pm3x^2 - 8x + 5 = 5

x(3x-8) = 0

x = 0 or x = 8/3

I don't understand how you got your answers.
