Answer:
y = 4x, (Each x value will multiply by 4 to give y)
Explanation:
Notice the ordered pairs for the first few values.
(2, 8)
(4, 16)
(6, 24)
Every time the x value increases by 2, the y value increases by 8.
We can halve this to find, when x increases by 1, y increases by 4.
If you would like, try to find what the y value would be if x = 3.
