Use the graph or table to write a linear function that relates to y to x. I need help on answering number 8, please and thank you!

y = 2/1 x 0

Step-by-step explanation:

Y=mx+b

2 and 1 are the “rise and run” (m) (from one point to the next, you must go up 2 units then right 1 unit)

The y intercept (b) is the point where it is on the y axis but 0 on the x axis, so 0

its line 2 i just added the rest or else it wouldn't let me answer
