Answer: Simplify 8/10 which is 4/5.
Step-by-step explanation:
Given:
The function is:

To find:
The inverse of the given function, then draw the graphs of function and its inverse.
Solution:
We have,

Step 1: Substitute
.

Step 2: Interchange x and y.

Step 3: Isolate variable y.


Step 4: Substitute
.

Therefore, the inverse of the given function is
and the graphs of these functions are shown below.
Answer:
the required slope of the points is -1...
i guess is by multiplying 3by the first equation and multiply 2by the second equation
3x+8+4x=-8x+48–104x–40
7x+8=-112x+8
-7x -7x
8=-119x+8
-8 -8
0=-119x
0=x
