Question

Which representation shows a proportional relationship between x and y? (2017) show all work for tables

Answer 1

Answer:

Understand that a relationship between two variables, x and y, is proportional if it can be expressed in the form yx = k or y = kx. Distinguish proportional relationships from other relationships, including inversely proportional relationships (xy = k or y = kx).

For example: The radius and circumference of a circle are proportional, whereas the length x and the width y of a rectangle with area 12 are inversely proportional, since xy = 12 or equivalently, y = 12x.
