Find the equation of all lines having slope 2 which are tangent to the curve

Answer:

Given curve is             ?.. (1)       Let P(h, k) be a point on (1)           ? (2)             Given that slope of tangent to the curve (1) is m = 2.                          h is not real.       Hence there is no tangent to (1) having slope 2.
