Question

How do you know that the table and the equation represent the same proportional relationship between x and y

Answer 1

If the x values increase or decrease constantly and if the y values increase or decrease constantly. Ex

x. y
2. 3
4. 6
6. 9

in this example the x values are increasing by 2 every time while the y values are increasing by 3 every time. note that the increase or decrease of the x and y values dont have to be the same
