Find the slope of the line passing through (1,2) and (4,8).

Explanation:
Slope is rise over run—the vertical change divided by the horizontal change between two points. From (1, 2) to (4, 8), the vertical change is 8 − 2 = 6 and the horizontal change is 4 − 1 = 3. So the slope is 6/3 = 2. This means the line rises 2 units for every 1 unit it moves to the right. The other possible values would require different rises or runs, but these two points fix the ratio at 2.
