Here is an expression 3*2t.

Evaluate the expression when t is 1

Well if t is equal to 1, then it would be 3*2*1. And since the one can basically be disregarded, the answer would be 3*2

The answer would he -4,-2 because the points are just on the opposite side. since the x axis is +4 it's going to he -4 and since the y axis is -2 it stays there because whaen rotated it stays in the third quadrant
