Question 66101: Find the slope of any line perpendicular to the line through points (0,5) and
(-3, -4).
what i've done so far is the following:
m= -4-5/ -3 - 0 = 9/3=3
I don't know how or what am i suppost to do the rest.

You can put this solution on YOUR website!

What you have done is perfectly fine.
You have found the slope of the line through the given points.
Slope = 3
Slope of any line perpendicular to this line = -1/3
Thus the slope of any line perpendicular to the line through points (0,5) and (-3, -4) is given by -1/3


Good Luck!!!

The key here is remembering that perpendicular lines have slopes that are the negative reciprocal of each other.
So, if your first line has a slope of 3, then any line that is perpendicular to this will have a slope that is the negative reciprocal of 3 or -1%2F3
