Answer:
The right answer is Option 2:

Step-by-step explanation:
Point-slope form of equation of a line is given by:

Here m is slope of the line and (x1,y1) is the point from which the line passes.
Given
Slope = m = -3/4
Point = (x1,y1) = (2,-6)
We simply have to put these value into the general form of equation of line in point-slope form

Hence,
The right answer is Option 2:

F^-1(x)=12+x hope this is what you need
Average Rate of Change is given by the Slope of the Function
We know that :
✿ 
The Given Points are : (3 , -10) and (5 , -26)
Here : x₁ = 3 and x₂ = 5 and y₁ = -10 and y₂ = -26

✿ Option C is the Answer
