Answer is y = 1/2x + 2
Step-by-step explanation
Slope intercept form is y= mx + b
M is slope and B is y intercept
On the graph you can see the line crosses the y axis at 2, this is B the y intercept
On the graph slope is rise/run from one point to another, as shown is rise +1 and run +2, so slope (m) is 1/2. See attachment.
