slope of perpendicular lines are ALWAYS OPPOSITE RECIPROCAL of the original slope

The original slope given is: $3/4x$

The Perpendicular slope is: $-4/3x$

Notice how the new slope is the reciprocal of the original slope and is opposite in terms of its sign.

How do you find the slope that is perpendicular to the line y =(3/4)x-7y =(3/4)x-7?
