Answer:

No

Explanation:

  • because if we put x=1 in equation y=x+3.75
  • y=(1)+3.75
  • y/x=4.75
  • if that is proportional then y/x will be same in each scenario
  • and if we put x=2 then y=(2)+3.75
  • y=5.27
  • y/x=2.875
  • so it is not equal, it mean that relation is not proportional

Answer:

NO

Explanation:

if we plug in 1 = x, we get 4.75 = y. If this is proportional, then y/x will be the same in each scenario.

Let's plug in 2 = x to get y = 5.75. 5.75/2 = 2.875 DOES NOT EQUAL 4.75/1 = 4.75.

That means that the relationship is NOT proportional.

The easier way to tell is to see that there is a number being added, so it can't be a proportional relationship.
