For this case we have the following equation:

We manipulate algebraically to bring the equation to the slope-intersection form y = mx + b
Where:
m: It's the slope
b: It is the cut-off point with the y axis

By definition, if two lines are parallel then their slopes are equal.
Thus, the line is of the form:

We find the cut-off point by replacing the given point:

Thus, the line is of the form:

Answer:

A. Step 1
There should be no radicals in the equation
That's the last one because you can factor to get
(x + 8)^2 = 36
(x + 8) = +/- 6
