Consider the parametric curve defined by the image of r(t) = (-7t, 13 – 8t). (a) Find the velocity and speed of the parametric curve whent = -1. Velocity = Speed = (b) Find an equation for the tangent line (in terms of z and y) to the image of the parametric curve when t = -1 (C) Find d?y/dr when t = -1 d'y Using the concavity information provided by d?y/dr2, is the parametric curve above or below its tangent line when t = -1? Choose
