IN NEED OF HELP PLEASE !!! ALSO EXPLAIN PLEASE

Answer 1

Answer:

  $\dfrac{1-10}{8-5}$

Step-by-step explanation:

The average rate of change between two points on a graph is ...

  average rate of change = slope = rise/run

The rise over the given interval is the function value at x=8 less the function value at x=5. That is, ...

  rise = 1 - 10

The run is the difference in the x-values:

  run = 8 - 5

Then the average rate of change is ...

  average rate of change = rise/run = (1 -10)/(8 -5)

_____

Here, the points are written as (x, y), so the only pair we're interested in is ...

  (5, 10) and (8, 1)
