Question 370216: determine whether the pair of lines x-2y=7 and y=-2x+5 are parallel, perpendicular, or coincide

The 2nd equation is the same as 2x+y = 5. Any line perpendicular to this line must have the equation x -2y = c, where c is a constant. Since the first equation has this form, the pair of lines are perpendicular.
