Answer:
y = 2.5x
Step-by-step explanation:
Note where all the points are.
When x = 0, y = 0
When x = 2, y = 5
When x = 8, y = 20
You simply need to find how much "y" is for each "x". Divide y with x:
5/2 = 2.5
Check. Plug in the x, and obtain the y:
y = 2.5x
y = 2.5(4) = 10 (True).
y = 2.5(8) = 20 (True).
