Question

The quantities x and y are proportional find the constant of proportionality (r) in the equation y=rx 8 1.6 15 3 22 4.4

Answer 1

r = 0.2

Explanation:

Given

y = rx ( divide both sides by x )

`(y)/(x)` = r

Use any of the ordered pairs from the table and substitute

Using (8, 1. 6 ) , then

r =
`(1.6)/(8)` = 0.2
