Question

Point A is located at (4,-7). If A is reflected in the x-axis, its image will be located at...

a) (4,7)
b) (-4,-7)
c) (7,4)
d) (-4,7)

Answer 1

When a point is reflected in the x-axis, the y-coordinate changes sign while the x-coordinate remains the same. Therefore, the image of point A at (4, -7) reflected in the x-axis will be located at (4, 7).

Step-by-step explanation:

When a point is reflected in the x-axis, the y-coordinate of the point changes sign while the x-coordinate remains the same. In this case, point A is located at (4, -7). So, when A is reflected in the x-axis, the x-coordinate remains the same as 4, but the y-coordinate changes sign to become positive. Therefore, its image will be located at (4, 7).
