1. The problem statement, all variables and given/known data Find a parametric equation for a part of a parabola. Given: y=-2x2 initial point: (-2,-8) terminal point: (1,-2) 2. Relevant equations x(t)=a+t(c-a) y(t)=b+t(d-b) 3. The attempt at a solution x(t)=-2+t(1-(-2)) =3t-2 y(t)=-8+t(-2-(-8)) =6t-8 I'm not sure where to go from there.
