We found this function by finding each part of the linear equation that is y = mx + b. First, we found m which is the slope by using the equation m=(y2-y1)/(x2-x1). Then we found that the slope is 1. Then from this, we watch the graph and find the y-intercept that in this case is 2. Then we replaced these values and ended up having the equation y = 1x + 2.
