Answer: 2/3
Explanation:
1) First locate two points.
First, locate two points on the graph. For this example, I will choose (-2,0) and (1,2)
2) Find the distance between these two points.
We can find that from starting from (-2,0), we go right 3 and up 2. You can easily do this on paper by drawing a triangle.
3) Using the numbers we have before, find the rate.
To find the rate, we can use rise/run. Which will become 2/3.
