Question

Is this equation proportional or non-proportional? How do you know? y = 7x - 3

Answer 1

Answer:

Step-by-step explanation:

This is not proportional.

There are two ways you can tell

• The y intercept must be 0. In this equation, the y intercept is -3
• y/x should be the same for all correct values of y given x.

Examples

x = 3

y = 18

y/x = 6

x = 2

y = 11

y/x = 11/2 = 5.5
