Apoint that is 7 units from the y-axis is reflected across the y-axis. what is the distance of this new point from the y-axis? explain how you know.

7 units  

Step-by-step explanation:

When you reflect a point (x, y) across the y-axis, the y-coordinate remains the same, but the x-coordinate gets the opposite sign: it becomes (-x, y).

Thus, if a point A, say, (-7, 5) is seven units to the left of the y-axis, its reflection A' will be the same distance to the right, at (7,5).

In the image below, Point A is seven units to the left of the y-axis. Its reflection, Point A', is seven units to the right of the axis.

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3
