x = -4
Step-by-step explanation:

Lets divide both the sides by -3.


Maybe the money you owe someone
Ok so you have $685 plus an extra $85 for the installation. You have a total of $770. You divide this by two to find per year. It is $385 per year. Now divide that by twelve for the monthly cost and you get $32.08
The equation of the line in point-slope form is given by:

Where,
(xo, yo): point that belongs to the line
m: slope of the line
The slope is given by:

Substituting values:

Rewriting:

Now we choose an ordered pair:

Substituting values we have:

We now rewrite the equation in its standard form:

Where,
b: cut with the y axis.
We have then:
Answer: point-slope form: 
or
standard form
X is equal to or greater than 3:
Plot x = 3 on the x-axis (horizontal axis). Then, beginning at x = 3, draw an arrow from there to the right.
