Question

does y vary directly with x? if it does, write an equation for the direct variation.

x = 10, 16, 20
y= 15, 24, 30

I need help pls I don't understand.

Answer 1

well, for the 20 and 30
y = (3/2) x = 1.5 x
does that work for
24 = 1.5 * 16 ?
and for
15 = 1.5 * 10 ?

if so then y = 1.5 x, a direct variation, is it.
