Answer:
y= 1/2x - 1
Step-by-step explanation:
You are using the formula y=mx+b where m is your slope and b is your y-intercept. By looking at the graph you can see the line passing through -1 on the y-axis which you would put as your b. For you slope, m, you see how many times you go up and to the side between two points, commonly known as "rise over run". On the graph you are going up, rising, one unit and moving to the right, running, 2 units, and that is how you would get the slope of 1/2. TIP: your rise always goes over your run! hence the "rise OVER run"
And all together you would get y=1/2x -1
