Question

The point (11,9.5) is reflected across the y -axis on a coordinate plane to create a new point. What is true about the new point? Select the answers from the drop-down lists to correctly complete each sentence. The new point is located at . The distance between the two points is units.

Answer 1

Answer: (-11, 9.5), 21

Explanation:

If you reflect a point across the y-axis, the x coordinate will change signs.

To distance between the two points is a straight line, (since the y coordinate remains the same), so the distance is 2 x 11 = 21
