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:

Answer:
$ 746.16
Step-by-step explanation:
MONTHLY interest = .0335/4
4 years = 48 months
500 ( 1 + .0335/4)^48 = 746.16
The equation factors as
.. (x +3)(x +4) = 0
By the zero-product rule, the roots are
.. x1 = -4
.. x2 = -3
