On the plane curve defined by the parametric equations below, what point corresponds to t= -1

Anton [14]

The equation x=2t-1 represent the x-coordinate. To get the value of x, substitute t with -1.

That is: x = 2(-1) - 1
= -2-1
= -3
Likewise, the equation y=t∧-3 represent the y-coordinate. Substituting t with -1,

y = (-1)∧-3
= -1

The point that correspond to t=-1 is (-3,-1).
