Find the equation of the chord of a parabola joining the points 1 and -3 with parameters x=2t and y=t^2

I'm assuming you mean x = 1 and x = -3? Get the Cartesian equation of the parabola, find the coordinates of the two points and find the equation of the line joining those two points.

From which source did you take such a poorly worded question? I'm assuming differently to Trebla - that the points have parameters t=1 and t=-3.

x=2t and y=t^2 are the parametric equations, not the parameters.

Ahahaa from Cambridge. I reckon you're right actually. That clears stuff up. Thank you guys!!!
