Answer:
Answer: B) Y = 2x
Step-by-step explanation:
The pattern of the proportional relationship is every 1 move on the "X" line moves up 2 places in the "Y" line. Notice that the first mark is (1, 2) and the second mark is (2, 4), and the third mark that you see on the graph is (3, 6). Notice that you add 2 on the "Y" axis every time you move once on the X-axis. If you multiply 2 x what ever number is on the horizontal line (X), you will get the next point in the proportional relationship. 1 x 2 = (1, 2), 2 x 2 = (2, 4), and 3 x 2 = (3, 6). Therefore, the answer is B) Y = 2x
