For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis.
According to the statement data we have:
Thus, the equation is of the form:
We substitute the given point and find the cut-off point:
Finally, the equation is:
We manipulate algebraically to obtain the standard form:
We multiply by 3 on both sides of the equation:
We multiply by -1 on both sides:
Answer:
The inverse of this function is y =
In order to find the inverse of any function, you must start by switching the y and x terms. After doing so, you can then solve for your new y. The result will be the inverse function. The work for this one is done below for you.
y = 3x + 2----> switch the x and y
x = 3y + 2 ----> subtract 2
x - 2 = 3y ----> divide by 3
= y ----> switch the order for consistency
y =
This is now your inverse function.
