2. Which point lies on the graph represented by the equation 3y + 2x = 8? (1) (-2,7)
(2) (0,4)
(3) (2,4)
(4) (7,-2)

4) (7, - 2)

Step-by-step explanation:

A point that lies on the graph of 3y + 2x = 8 is a solution of this equation. Substitute each ordered pair into the equation to find the correct answer.

1: (-2, 7)

59 is not equal to 8 so this answer is incorrect.

2: (0, 4)

12 is not equal to 8 so this answer is incorrect.

3: (2, 4)

16 is not equal to 8 so this answer is incorrect.

4: (7, - 2)

This ordered pair satisfies the equation so this is the correct answer.

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
