Question

Point C(9,4) is reflected across the x-axis.
What is the y coordinate of the image of point C?

Answer 1

The y-coordinate of the image of point C(9,4) after reflection across the x-axis is -4.

Step-by-step explanation:

When point C(9,4) is reflected across the x-axis, the x-coordinate remains the same but the y-coordinate changes its sign.

So, the y-coordinate of the image of point C after reflection will be -4.
