Answer:
2
Explanation:
The slope is equal to the rise/run of the line, or in other words, the number of units it travels up over the number of units it travels right. We can see on the graph that for every time it travels right 1 unit it travels up 2 units, so the rise/run is 2/1. 2/1 is equal to 2, so therefore, the slope of the line is 2.
