Question

Which explains whether or not the graph represents a direct variation?

Answer 1

Step-by-step explanation:

if the graph is a straight line passing through origin , it represents direct variation

Answer 2

A graph shows direct variation if it goes through the origin,

(0,0)

The equation is

y=kx , where k is a constant, which is apparent when we write the equation as

yx=k

. In slope-intercept form, the equation would be

y=mx+b , where

m=k

and

b=0 .
