You can perform the horizontal line test on the original to see if the inverse will be a function. You will not perform the horizontal line test on the inverse.
I'm not sure what the equation would be, but its the number multiplied by two, and It keeps accumulating so maybe yx2?
16r^2+ 2r -4r
16r^2 - 2r
2r ( 8r -1)
Answer:
X = 100$ + 5a$
Where X is the price of a car rent
And a is the amount of mile travel
Given:
The inequality is:

To find:
The y-intercept, slope and type of line (solid or dotted).
Solution:
The slope intercept form of a line is:
...(i)
Where, m is the slope and b is the y-intercept.
We have,

The relation equation is:
...(ii)
On comparing (i) and (ii), we get


It means the slope is 5 and the y-intercept is 3.
The sign of the inequality in the given inequality is ">". It means the boundary line is not included in the solution set. So, the boundary line is a dotted line.
Therefore, the slope is 5, the y-intercept is 3 and the line is a dotted line.
