Graph the proportional relationship y = 2x by plotting points. Which graph is right?

Graph A. (2, 4) (1, 2) (0, 0)

Graph B. (1, 4) (0, 0)

Graph C. (2, 6) (1, 3) (0, 0)

Graph D. (2, 1) (0, 0)

1 answer

Graph B is correct.

When x = 1, y = 2(1) = 2
When x = 0, y = 2(0) = 0

Therefore, the points (1, 2) and (0, 0) plot the proportional relationship y = 2x.
