Find the slope of the line determined by these two points:  A(-5,2) and B(2,-2)

anonymous · Answer

do i label it on a graph

directrix · Answer

No. Just get the numerical value of the slope. Just as you did before. Change in y over change in x.

anonymous · Answer

These are the answer choices

A.) Yes, there slopes are different
B.) No, their slopes are not opposite reciprocals  
C.) No, there slopes not the same 
D.) Yes, there slopes are opposite reciprocals

I cannot give you the answer.

If you would find this slope, -->Find the slope of the line determined by these two points: A(-5,2) and B(2,-2) then we would be on our way to the answer.

how to find the slope @Directrix

anonymous · Answer

rule for 2 lines being perpendicular to each other, compare their slopes.
