how do i find the slope of a line perpendicular to a line containing (-5,1) and (-3,-2)

Question

anonymous · Answer

How do you find a slope of a line when you are given two points?

anonymous · Answer

y-y over x-x?

anonymous · Answer

Yes, then you can find a slope of a line that passes those two given points.

What is a characteristic of a line that is perpendicular to another line? (Hint: Slope)

anonymous · Answer

they intersect

anonymous · Answer

There's something more important having to do with slope of those two lines!

For example, when two lines are parallel, their slopes equal to each other. 

Then if the two lines are perpendicular... their slopes are?

anonymous · Answer

opposite!

anonymous · Answer

Close... they are opposite reciprocals of each other!

If slope of a one function is -2, then the slope of another line that is perpendicular is 1/2

Remember this now eh?

anonymous · Answer

so i find the slope if the line given then flip it and its sign?

anonymous · Answer

Yep, that will give you the answer to the problem right away!

ty so much!
