Answer:
Slope = 1
Step-by-step explanation:
The slope of a line can be calculated using two points in the line (x1, y1) and (x2, y2) as follows:

Then, if we take two points in the line like (0, 3) and (2, 5) and we replace (x1, y1) and (x2, y2) respectively, we get that the slope is equal to:

So, the slope of the line on the graph is 1
