  not proportional -- the y-intercept is not zero

Step-by-step explanation:

A quick check of table values shows the relationship is not proportional:

  100/2 = 50 ≠ 45 = 180/4

That is, the ratios of table values are not constant.

When the values are graphed, the line through the points does not intersect the origin. This is further indication the relationship is not proportional.
