In calculus, we use derivatives to find the instantaneous rate of change at any point on a graph. To find the average rate of change, we just find the slope of the secant line that intercepts two points on the graph.
We find slope with the following equation:

In this case, we are looking for the slope from x = -1 to x = 1. We have both x values, so next we need the y values.
F(-1) = (-1)^2 - (-1) - 1 = 1
F(1) = (1)^2 - (1) - 1 = -1
Now plug in the x and y values to find the slope:
The answer is -1.
Answer:
3/5

Answer:
yes
Step-by-step explanation:
-8x-2y<6
put in x and y and see if it is less than 6
-8(3) -2(2) <6
-24 -4 <6
-28 <6
yes
it is a solution
Answer:
C. y<3
Step-by-step explanation:
We are required to determine the solution set of the inequality

Step 1: Add 9 to both sides

Step 2: Divide both sides by 15

The solution set of the given inequality is: y<3.
The correct option is C.
