Answer:Slope is 2, assuming "0,0 and 2,4" is meant to read (0,0) and (2,4) for the 2 points.
Step-by-step explanation:
The slope is the Rise (change in y) over the Run (change in x). I can see the change in y is 4 (it goes from 0 to 4) and the change in x for this interval is 2 (goes from 0 to 2, or 2-0 = 2). Rise (4) over Run (2) is slope 2. 4/2 = 2 slope.
