The student flipped the slope and the y-intercept. The slope should be 2, and the y-intercept should be 3.
Work Step by Step
The given line is in the form $y=mx+b$. Thus, we first identify the value of b, which is where the graph crosses the y axis, and plot it. Then, starting at this point, we use the slope, m, to graph the rest of the line. (For instance, if the slope is 3, start at the y intercept, and then go three up and one over to find the next point. At this point, you would have two points and could thus connect them to create the line.)
