Question

Is the line passing through points A(-5,2) and B(2,-2) perpendicular to the line passing through points C(0,5) and D(4,12)

Answer 1

@Directrix

Answer 2

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

Answer 3

do i label it on a graph

Answer 4

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

Answer 5

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

Answer 6

@Directrix

Answer 7

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.

Answer 8

how to find the slope @Directrix

Answer 9

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