Hello, hope you are having a nice day.

Perpendicular lines have slopes that are opposite reciprocals (the opposites of a number flopped over)

-1/4 (the slope of the given line)

The slope of the line perpendicular to the given line is:

The opposite of -1/4 is 1/4.

1/4 flopped over is 4/1 or 4.

So the slope is 4. Hope it helps.

Answer:

A line is perpendicular to

y = - 1/4x-9

comparing with y = MX+ c

m=-1/4.

slope =-1/4
