sketch the curve represented by the parametric equations. Then eliminate and write the corresponding rectangular equation whose graph represents the curve.
10. x=t2-6
y=1/2t-1
10. x=t2-6
y=1/2t-1

well, t = 2y+2, so use that

how do I use
t = 2y+2?

come on. just substitute it into the other equation.
t = 2y+2
x = t^2-6 = (2y+2)^2-6 = ...
It is clearly a horizontal parabola

x = t^2-6 = (2y+2)^2-6 = ...
