LetCbe the curve of intersection of the parabolic cylinderx2 = 2y, and the surface 3z=xy. Find the exact length ofCfrom the origin to the point (5, 25/2, 125/6).

My instructor told us to put those equations in parametric form so we could use the arc length formula, but I am not sure how to put those in that form.

I know that these are the equations I must use, but how do I solve for t from the 2 equations I'm given??

x = x_o - at

y= y_o - bt

z = z_o - ct
