Answer:

6) C 1

7) A 3 (im not sure for this one because it's blurry)

8) C 1

Step-by-step explanation:

6) Replace the f(x) for -1 since we are told f(x) = -1. We then need to use the inverse operation to get x by itself.

[tex] - 1 = \frac{x - 3}{ 2} [/tex]

Since the opposite of division (which is indicated by the fraction line) is multiplication, we need to multiply the number on the left (-1) times 2.

[tex] - 2 = x - 3[/tex]

For this step, the opposite of subtraction is addition so in this step, we must add 3 to -2.

[tex]1 = x[/tex]

7) Can't explain cause I'm not sure if I'm right

8) To find out the slope of two coordinates we must use the following to determine it.

(IN THE PICTURE ATTACHED)

In this case, the y with the little two will be 4 and the y with the little one is 1. 4-1 is 3 and that's the y cooridnate sorted

For the x coordinate, the x with the little two is 1 and the x with the little one is -2. Thus, we must solve 1-(-2) which also equals 3.

Since the final coordinates are 3/3 and it simplifies, the final answer is 1.
