27, 140 is the correct answer
A linear equation is represented as:
.
The equation of the line is: 
First, we calculate the slope (m) of 
Make y the subject

Divide by 18

In 
slope
So, the slope of
is:

Since, the line is perpendicular to 
The slope of the line is:

So, we have:


The line passes through (4,-2).
So, the equation is:

This gives:



Hence, the linear equation is:
