Answer:

(6, 1) ⇒ y = 2/4x - 2

(-8, -0.8) ⇒ y = 3/5x + 4

(9, 0.7) ⇒ y = 3/10x - 2

(2, 7.4) ⇒ y = 1/5x + 7

Explanation:

Let's substitute each pair in the equations to find the right one :

(6, 1)

⇒ 1 = 2/4 (6) - 2

⇒ 1 = 3 - 2

⇒ 1 = 1

Equation matched √

(6, 1) ⇒ y = 2/4x - 2

(-8, -0.8)

⇒ -0.8 = 1/5 (-8) + 7

⇒ -0.8 = -8/5 + 7

⇒ -0.8 = -1.6 + 7

⇒ -0.8 = 5.4

Incorrect equation ×

⇒ -0.8 = 3/5 (-8) + 4

⇒ -0.8 = -24/5 + 4

⇒ -0.8 = -4.8 + 4

⇒ -0.8 = -0.8

Equation matched √

(-8, -0.8) ⇒ y = 3/5x + 4

(9, 0.7)

⇒ 0.7 = 3/10 (9) - 2

⇒ 0.7 = 27/10 - 2

⇒ 0.7 = 2.7 - 2

⇒ 0.7 = 0.7

Equation matched √

(9, 0.7) ⇒ y = 3/10x - 2

(2, 7.4)

⇒ 7.4 = 1/5 (2) + 7

⇒ 7.4 = 2/5 + 7

⇒ 7.4 = 0.4 + 7

⇒ 7.4 = 7.4

Equation matched √

(2, 7.4) ⇒ y = 1/5x + 7
