graph of the equation 2y - 3x = 21
O (-5,3)
O (2,13.5)
0 (0,-2)
O (-7,0)
O (3,-4)
O (6,4)

Answer 1

Answer: The points that are on the graph of the equation 2y - 3x = 21:

• (-5,3)
• (2,13.5)
• (-7,0)

Explanation:

The easier way it's plug the point into the equation.

1. (- 5 ,3) x = - 5; y = 3

2(3) - 3(-5) ?= 21

6 + 15 ?= 21

21 = 21 √

1. (-5,3)

x = -5; y = 3

2(3) - 3(-5) ?= 21

6 + 15 ?= 21

21 = 21 √

2. (2,13.5)

x = 2; y = 13.5

2(13.5) - 3(2) ?= 21

27 - 6 ?= 21

21 = 21 √

3. (0,-2)

x = 0; y = -2

2(-2) - 3(0) ?= 21

- 4 - 0 ?= 21

-4 = 21 ×

4. (-7,0)

x = - 7; y = 0

2(0) - 3(-7) ?= 21

0 + 21 ?= 21

21 = 21 √

5. (3,-4)

x = 3; y = -4

2(-4) - 3(3) ?= 21

-8 -9 ?= 21

-17 = 21 ×

6. (6,4)

x = 6; y = 4

2(4) - 3(6) ?= 21

8 - 18 ?= 21

-10 = 21 ×
