Question

/// please answer!! //

If a preimage is (0,1), (4,0), (4,1), what are the points after a translation of 3 units up and then a reflection over the y-axis?

a.) (-3,0), (-3,4), (-4,4)

b.) (0,-1), (4,0), (4,-1)

c.) (0,3), (4,3), (4,4)

d.) (0,4), (-4,3), (-4,4)

Answer 1

d.) (0,4), (-4,3), (-4,4)

Explanation:

Answer 2

D

Explanation:

The question firs states that the points are moved three points upwards. This means that each point has an increase of the y value by three points.

This gives us the points (0,4), (4,3) and (4,-4)

Reflecting them across the y-axis, it means that their height will stay the same. but the x value will be on the other side of the x- axis.

This leaves us with the answer D.

Note that the first point stays the same because it is on the y-axis, it doesn't get reflected.

Hope this helps.
