Question

Is each line parallel, perpendicular, or neither parallel nor perpendicular to the line −3x+5y=−15 ?

Answer 1

Perpendicular means that it has a slope that is the reciprocal of the original, and parallel means that the slopes are the same.

Answer 2

Tip:

With these kinds of equations focus on the x and y values

Same exact values = parallel

x and y values are swapped = perpendicular

anything else = neither
