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 \$\displaystyle y'=2~?\$

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

oh that simple

y-0 = 2(x - 2)
