Question

reflect △abc across the x - axis by answering the questions below and plotting the necessary points.

1. how many units away from the x - axis is point a?
2. the image of a will be 2 units away from the x - axis along the vertical line x = - 4. plot a.
3. how many units away from the x - axis is point b?

Explanation:

Step1: Identify point A's y - coordinate

By observing the graph, point A is 2 units above the x - axis.

Step2: Apply reflection rule

When reflecting a point across the x - axis, the x - coordinate remains the same and the y - coordinate changes its sign. Point A is on the line x=-4 and 2 units above the x - axis. Its image A' will be on the line x = - 4 and 2 units below the x - axis.

Answer:

Point A is 2 units away from the x - axis. The coordinates of A' are (-4,-2).
