Answer:
the slope is the rise over run, or in other words, 2/1. The y intercept is where the line meets the y axis. On the graph, find 4 on the y axis and mark it as a point. from there, rise 2 (move up from the y intercept, or 4, 2 spaces) and from the 2 up, run (or move over 1) 1. Let me know if this helps!
