The slope of the line in the graph is 2.
let's find the slope:
If a line passes through two points (h, k) and (a, b), then the slope is given by:
m = (a - h)/(b - k)
In the graph we can identify the points (0, 1) and (1, 3), then the slope of this line will be:
m = (3 - 1)/(1 - 0) = 2
The slope is 2.
