(will give brainliest) which graph represents a function with direct variation?

the last picture.

Justification:

Direct variation means that the ratio of the variables is constant, i.e. y / x = k or, equivalently, y = kx.

That means that the graph of a function with direct variation has these features:

Since the only graph that is passing through the origin (0,0) is the last graph, it is the only graph that represents a function with a direct variation.

if x decreases by 4 then y increases by 10

step-by-step explanation:

actually what is a question i don't understand
