To solve such problem and many other similar problems related to parallel lines, simply substitute
the given coordinates of the point x= 5, y= 1 into left side of the equation and calculate the value of the expression
3*5 - 2*1 = 13.
Then the equation of the parallel line is
3x - 2y = 13. ANSWER
So you keep the left part of the equation "as is" and replace the right side constant by the new value.
That's all.
