Question

A(3, 4) and B(8, 9) are two points. C and D are the images of points A and B respectively about the origin. Find the coordinates C and D.

• A. C = (-3, -4), D = (-8,-9)
• B. C = (-3, 4), D = (-8,9)
• C. C = (3, -4), D = (8,-9)
• D. C = (3, 4), D = (8,9)

Answer 1

The correct option is A

C = (-3, -4), D = (-8,-9)

When a point is reflected in the origin, then the sign of both x and y coordinate changes. Therefore

Coordinates of C = (-3, -4)

Coordinates of D = (-8,-9)
