Question

The quantities x and y are proportional. Find the constant of proportionality (r) in the equation y=rx

Answer 1

y=rx 1/4/5/5/5

Explanation:

Answer 2

r =
`(1)/(2)`

Explanation:

The proportional equation is

y = rx ( divide both sides by x )

`(y)/(x)` = r

Substitute any ordered pair from the table

Using (14, 7 ) , then

r =
`(7)/(14)` =
`(1)/(2)`
