So first, you get the absolute value to one side:
Next, set up two equations; One where the value inside the absolute value lines is positive, and another where it is negative, and solve both for the variable:
Your answers are 8 and -8, or +-8.

Step-by-step explanation:
First find the slope:
Use the point-slope form of linear equation:
(where m is the slope and (x₁, y₁) is a point on the line)
with the found slope and one of the points:
