From the graph, the first point is (4, 2) and the second point is (8, 4).
We can say that the x value increases by 4 and the y value also increases by 2
Note that we can simplify 4 and 2 by dividing both by 2.
This will be :
4/2 = 2
2/2 = 1
So the x-values increase by 2 and y-values increase by 1.
The answer is B.
