-3 and -3

Answer 2

The answer to your question is letter D

Explanation:

Line equation y = x

A. (1, -1)

Substitute the point in the equation

-1 = 1

This point is not on the line because -1 ≠ 1

B. (4, 2)

2 = 4

This point is not on the line given because 2 ≠ 4

C. (-3, 3)

3 = -3

This point is not in the line given because -3 ≠ 3

D. (-3, -3)

-3 = -3

This point is on the line because - 3 = - 3
