Answer:

Explanation:
you are already partially there with finding the slope!
use the formula

rise means the height you are climbing upwards
run means the distance you are traveling sideways
you already determine that your rise = 2, and your run = 4.

to complete the slope-intercept form, you need the y-intercept. to find it, you set x=0

(we can see this based on the graph)
with all the components you can make your slope-intercept form!
