Question

Which ordered pair is a solution of the equation?
y= 7x - 3
Choose 1 answer:

Answer 1

3/7, 0

Explanation:

7x-3=0

7x = 3

x = 3/7

substitute

y = 7(3/7) - 3

7s cancel out

y = 3 - 3

y= 0

Answer 2

`(3)/(7), -3`

Explanation:

`7x-3=0`

`7x-3+3=0+3`

`7x=3`

`(7x)/(7)=(3)/(7)`

`x=(3)/(7)`

`\left((3)/(7),\:0\right)`

`y=7\cdot \:0-3`

`y=0-3`

`y=-3`

`\left(0,\:-3\right)`
