Tell whether the lines for each pair of equations are parallel, perpendicular, or neither.
y=-4x+3
and
-2x+8y=5
A. parallel
B. perpendicular
C. neither

I think parallel?

    Perpendicular.
    If you solve the system of equations, x= 19/34 and y= 13/17. The solution is their point of intersection. If there was no solution, they would be parallel.

    Thank you!

    two lines can intersect without being perpendicular ... like an X
