Use similar triangles to determine the slope of the line. Write your answer in fraction form.
The slope is ____.
The coordinates are (0, 0), (2, 1), (4, 2), (6, 3), (8, 4)
The slope is 1/2.
The ratio of the change in y-coordinates to the change in x-coordinates between any two points is always 1/2, so the slope of the line is 1/2.
