Explanation:
In order to graph the linear function, f(x) = ½x + 2:
Start by plotting the y-intercept, (0, 2) on the graph. Then, using the given slope, m = ½ (rise 1 unit, run 2 units), plot other points. Connect those points and create a line.
Attached is a screenshot of the graphed function, using the stpes highlighted in this post.
