Question

Help will give the brainliest hurry!!!!

Answer 1

Answer:

B

Step-by-step explanation:

A proportional function must include the point (0, 0).

That eliminates C and D.

The constant of proportionality is 0.8, so each y-coordinate divided by its corresponding x-coordinate must equal 0.8.

Try A:

0.5/4 = 0.125

0.125 is not equal to 0.8, so A cannot be the answer.

Try B:

4/5 = 0.8

8/10 = 0.8

10/12.5 = 0.8

Firs, B includes the point (0, 0). Also, for each ordered pair, the y-coordinate divided by the corresponding x-coordinate equals 0.8, so B is the answer.

Answer: B
