Find Equation of line tan to given curve with slope of 2

y = x^2 - 2x
slope of 2

so the equation slope of the given curve is 2x-2

not sure how to proceed any hints?

At what point is it true that $y'=2~?$

The point is $(2,0)$ the slope is $m=2$ so what is the equation of the tangent?

oh that simple

y-0 = 2(x - 2)
