Answer:
D
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is

Here { a, b ] = [ - 1, 2 ], thus
f(b) = 4 ← from (2, 4 )
f(a) =
← from (- 1,
) , thus
average rate of change =
=
=
→ D
Answer:
9
Step-by-step explanation:
To find the slope of a line, calculate the distance between points with a ratio of vertical to horizontal distance. This is done using the formula:

Here the points are (-7,-2) and (-6,7). Substitute and simplify.

$10.62? Im not sure if its correct
A point has a positive x and y coordinate- answer is Quadrant I
Answer:
0
Step-by-step explanation:
The y's are the same so they do not go up or down so the slope is 0.
