A highway is shown as a straight line on a coordinate grid. One end of the highway is located at (5, 9) and the other end is located at (3, -7). Sam performed the steps shown to find the coordinates of the midpoint of the highway.

Step 1. x1 = 5, y1 = 3, x2 = 9, y2 = -7
Step 2.
Step 3.
Step 4.
Step 5. x = 7, y = -2

In which step did Sam first make an error?
