Answer
1/2
Work Step by Step
The student found the run over the rise instead of the rise over the run. Slope equals rise over run. In order to find slope, we consider the rise and the run between the two points on the graph. Between the two points, we go one up, so the rise is 1. Additionally, we go right 2 units, so the run is 2. Thus, we get an answer of 1/2.
