A line passes through (1, 2) and (3, 8). What is its slope?

Explanation:
Slope is the rate of change of y with respect to x, found by rise over run between two points. From (1, 2) to (3, 8), the rise is 8 − 2 = 6 and the run is 3 − 1 = 2. So slope = 6/2 = 3. This means for every 1 unit to the right, the line goes up 3 units. The given coordinates produce a slope of 3.
