1 answer

To determine the slope of the line, we need to find the change in y-coordinate (vertical) divided by the change in x-coordinate (horizontal) between any two points on the line.

Let's take the points (0,0) and (1,2) as our two points. The change in y-coordinate is 2 - 0 = 2 and the change in x-coordinate is 1 - 0 = 1.

Therefore, the slope of the line is 2/1 or simply 2.
