Question

Which is the direct linear variation equation for the relationship?

y varies directly with x and y = 10 when x = 2.

A. y = 2x + 6
B.y = x + 8
C.y = 5x
D.y = x– 8

Answer 1

can any of u guys help me? :)

Answer 2

Yup when y varies directly with x the equation has the form:
y=kx where k is a constant of variation
So which of these 4 equations has the form y=kx

Answer 3

C

Answer 4

Ya got it :)
