Question

think about the process the relationship between x and y is represented by the equation y=19x how can you decide if the equation represents a porportianl relatingjip

Answer 1

Since the value is always multiplied by the same factor(19), the relationship is proportional.

Explanation:

To see if the equation represents a proportional relationship, we see if the division of y by x is always the same

`x = 1, y = 19*1 = 19`

`x = 2, y = 19*2 = 38`

`x = 3, y = 19*3 = 57`

So

`(57)/(3) = (38)/(2) = (19)/(1) = 19`

Equal, so proportional
