Question

Can someone help me please?

Answer 1

• B) y = 0.6x

Explanation:

Proportional relationship equation:

• y = kx, where k- coefficient of proportionality.

Use given values in table to find the value of k:

• 9 = 15k ⇒ k = 9/15 = 0.6
• 7.2 = 12k ⇒ k = 7.2/12 = 0.6
• 1.5 = 2.5k ⇒ k = 1.5/2.5 = 0.6

So the equation is:

• y = 0.6x
