Question

Write an equation in standard form using only integers for a line that passes through the point (5,-6) and is parallel to the line: x=-9 enter a, b, and c where your answer is ax+by=c

Answer 1

First, x = -9 is a vertical line thru the point (-9,0).  Its slope is undefined, since we cannot divide by zero.  If the new line is to be parallel to x = -9, it too will be a vertical line.  If it's to pass through the given point (5, -6), then x = 5 is the equation of this new line.
