Answer:
The answer is that the student plotted each (x,y) point as (y,x)
Explanation:
If you look at the graph, you will notice that points aren't correct. The first point (200,207), the point is plotted as (207,200). The numbers are switched. The point is at 200 on the y axis and at 207 on the x axis, which is reversed from what the point should be.
