Question

Which graph represents a proportional relationship?

Answer 1

A does.



A is a proportional graph.
B is a curved line which isn’t constant.
C looks like a straight line but it isn’t.
D it is not starting that the origin 0,0 meaning that it isn’t proportional due to y=kx

Answer 2

Graph represented by option A.

Explanation:

We are asked to choose the graph that represents a proportional relationship.

We know that a proportional relationship is in form
`y=kx`, where k represents constant of proportionality.

We can see that graph represented by option A is the correct choice as the y-intercept is 0.

The equation of the graph represented by option A would be
`y=mx`, where m represents slope of line.

Therefore, option A is the correct choice.
