In which of the following graphs do you recognize a proportional relationship?(1 point)%0D%0AResponses%0D%0A%0D%0A%0D%0AImage with alt text: An illustration shows a coordinate plane with the horizontal axis and vertical axis labeled x and y, but the unit increments are not marked. The origin is marked as 0. Four points are plotted on the graph. The unmarked coordinates of the plotted points are left parenthesis 2 comma 1 right parenthesis, left parenthesis 4 comma 2 right parenthesis, left parenthesis 6 comma 3 right parenthesis, and left parenthesis 8 comma 4 right parenthesis. A solid arrow begins at the origin and passes through the four points and beyond.%0D%0A%0D%0A%0D%0AImage with alt text: An illustration shows a coordinate plane with the horizontal axis and vertical axis labeled x and y, but the unit increments are not marked.

The origin is marked as 0. An upward diagonal line is plotted on the graph. The unmarked coordinates of the upward line are left parenthesis 0 comma 3 right parenthesis, and left parenthesis 8 comma 10 right parenthesis. The line has an arrow at the end.

Answer 1

The graph that represents a proportional relationship is the third graph with the upward diagonal line.
