Select each correct answer

Answer 1

see explanation

Explanation:

to determine which of the ordered pairs are on the line, substitute the coordinates of the point into the left side of the equation and if the value obtained equals the right side then it lies on the line.

(
`(2)/(3)`, -
`(7)/(4)`)

2 + 7 = 9 ⇒ correct

(- 5, - 6 )

- 15 + 24 = 9 ⇒ correct

(1, -
`(3)/(2)`)

3 + 6 = 9 ⇒ correct

(- 1, 3 )

- 3 - 12 = - 15 ⇒ incorrect

The 3 ordered pairs

(
`(2)/(3)`, -
`(7)/(4)`), (- 5, - 6), (1, -
`(3)/(2)`)

All line on the line 3x - 4y = 9
