2. Find the slope of the line between (8, 6) and (20, -14)

Natalka [10]

Answer:

slopee = 5/3

Step-by-step explanation:

The slope of a line is defined by the rise (the change in y-value) divided by the run (the change in x-value). Here, the change in y-value is 6 - (-14) = 6 + 14 = 20. The change in x-value is 20 - 8 = 12. Therefore, the slope is 20/12 or (simplified) 5/3.
