Reflect ABC over the y-axis. A= (-1, 2) B= (2,1) C= (4,5)

Answer 1

To reflect a point or a shape over the y-axis, we need to change the sign of the x-coordinates while keeping the y-coordinates the same.

So, reflecting A=(-1, 2) over the y-axis, we get A'=(1, 2).
Reflecting B=(2, 1) over the y-axis gives B'=(-2, 1).
Finally, reflecting C=(4, 5) over the y-axis results in C'=(-4, 5).

Therefore, the reflected points are A'=(1, 2), B'=(-2, 1), and C'=(-4, 5).
