Answer:

1. Slope of -2

2. 35

Explanation:

To find a slope you must find two points on a line that are DIRECTLY on the lines of the graph. There are two points already chosen. The points are (0,4) and (2,0)

Now find the differences of the x and y values.

2 - 0 = 2

4 - 0 = 4

The difference of the x values is 2 and y is 4

Now put it in a fraction. The rule for slopes is rise over run or y/x.

4/2

Don’t forget to simplify!

Slope of 2

Now one must find if the slope is negative or positive.

To figure this out look at the line. If the line is going up, it’s positive. If it’s going down, it’s negative.

This line is going down so it’s slope is negative.

So the line has a slope of -2

F(x) and F(8) means that x is equal to 8.

So replace the x in the equation with 8 and then solve it.

First, exponents!

8^2 = 8 x 8 = 64

Now:

64 + 6/2

Now add:

70/2

70/2 = 35

Therefore, it’s 35!
