Need help answering this algebra nation question!
My name is Ann [436]

Answer:

Option 1, 2 and 4

Step-by-step explanation:

3x-4y-8= 12

3x-4y= 12+8 (bring constants to 1 side)

3x-4y= 20 (simplify)

For a point to be a solution of the above equation, substitute the x and y coordinates into 3x-4y and see if it equals to 20.

Option 1: (0, -5)

3(0)-4(-5)= 20

This is correct

2) (4, -2)

3(4)-4(-2)=20

This is correct

3) (8,2)

3(8)-4(2)= 16

This is incorrect.

4) (-16, -17)

3(-16)-4(-17)= 20

This is correct.

5) (-1, -8)

3(-1)-4(-8)= 29

This is incorrect.

6) (-40, -34)

3(-40)-4(-34)= 16

This is incorrect.
