Line "a" passes through points with coordinates (-3,5) and (0,0) and a line "b" passes through points with coordinates (3,5) and (0,0). Explain how you would determine whether lines a and b are parallel perpendicular or neither

Answer 1

They are not parallel because they do not have the same slope. They are not perpendicular because their slopes and not opposite reciprocals of each other. So... they are neither.

The slope for line A is -5/3 and the slope for line B is 5/3
