Determine whether the graphs of the given equations are parallel, perpendicular, or neither. Explain.

Question

Using these equations listed y= 6/7x+4 ; y=-6/7x-5

Answer 1

Parallel lines have equal slopes.

6/7 ≠ -6/7

If the lines are perpendicular, the product of their slopes equals -1.

(6/7)(-6/7) ≠ -1

What can you conclude from this?
