Question

Which graph(s) shows a proportional relationship?

Answer 1

Graph #3 shows a proportional relationship. Proportional relationships go through the origin (0,0)

Answer 2

Graph 3

Note the x and y placements

when x = 1, y = 5 (1 x 5 = 5)

when x = 2, y = 10 (2 x 5 = 10)

when x = 3, y = 15 (3 x 5 = 15)

etc.

Graph 4

When x = 2, y = 5 (2 x 2.5 = 5)

When x = 4, y = 10 (4 x 2.5 = 10)

etc.

hope this helps
