slope = 4
Explanation:
The slope of a straight line is
Let's pick the points (1,2) and (3,10). (any two points will work)
Starting at a y-value of 2, you had to "rise" up 8 units in the positive y-direction to get to a y-value of 10. Starting at an x-value of 1, you had to "run" over 2 units in the positive x-direction to get to an x-value of 3. The rise is 8 and the run is 2.
So, the slope is:
slope =
slope =
slope = 4
