Question

What’s the answers for 6 and 7

Answer 1

6. (-8, 32), (5, -7), (0, 8)

7. (0, -2), (3, 13), (-9, -47)

Explanation:

6. y = -3x+8

(i) (-8, ___ )

Substitute the value of x in the equation:

⇒
`y = -3(-8)+8`

⇒
`y = 24+8`

⇒ y = 32

(ii) (5, ___ )
Substitute the value of x in the equation:

⇒
`y = -3(5) + 8\\`

⇒
`y = -15 + 8`

⇒ y = -7

(iii) (0, ___ )

Substitute the value of x in the equation:

⇒
`y = -3(0)+8`

⇒ y = 8

7. y = 5x - 2

(i) (0, ___ )

Substituting the value of x in the equation:

⇒
`y = 5(0)-2`

⇒ y = -2

(ii) (3, ___ )

Substituting the value of x in the equation:

⇒
`y = 5(3) - 2`

⇒
`y = 15-2`

⇒ y = 13

(iii) (-9, ___ )

Substituting the value of x in the equation:

⇒
`y = 5(-9) - 2`

⇒
`y = -45-2`

⇒ y = -47
