Since the line is parallel, the same coefficients can be used for x and y. The constant on the right needs to change so that the given point will satisfy the equation.
... 5x - 4y = 5(-8) -4(2) = -40 -8 = -48
Your equation is
... 5x -4y = -48
If I'm not mistaken its 7.2200
You have to find a common denominator. In this case it will be 486/324 = x/324. Then you would have to turn the 324 around. Then it will be 486/324 X 324. Which would be 486. Therefore. X = 486. Please tell me if I am wrong. Your welcome!
