Consider the line -4x-3y=-7. What is the slope of a line perpendicular to this line?

What is the slope of a line parallel to this line?

Slope of a perpendicular line:

Slope of a parallel line:

First get it into slope intercept form: y=mx+b m is slope and b is the y intercept

-4x-3y=-7
get y by it’s self
-3y=4x-7
divide by -3
y=-4/3x-7/3
so the of the original line is -4/3

the parallel line has the same slope so the parallel slope is -4/3
the perpendicular slope is opposite reciprocal of the original so it is 3/4

It’s hard to understand what you put.. can you show a picture ?
