Help please I-ready please

(2, 72)  (5, 180)

Step-by-step explanation:

To solve this, you have to plug in the x values in the ordered pairs into the equation so if it matches.

(2, 72)

y = 36(2)

y = 72

This one checks out.

(4, 40)

y = 36(4)

y = 144

This one does not apply.

(5, 180)

y = 36(5)

y = 180

This one also works.

The second row of answers does not apply because the x value will be less than the y value because you are multiplying the x value.
