Question

Find the slope of the line that is perpendicular to the line containing the points (-2,-1) and (2,-3)
A. m= -2
B. m= 2
C. m= -1/2
D. m= -1

Answer 1

i showed you the formula..its the same type of question

Answer 2

execpt, instead of finding a parallel slope, you have to find the perpendicular slope

Answer 3

Use the slope formula: y2-y1 over x2-x1

Answer 4

but when you find the slope, make sure to flip it since they are asking for the perpendicular slope

Answer 5

i got -1/5

Answer 6

(-2,-1) (2,-3)
-3-(-1) over 2-(-2)
-2 over 4= 1/2
your answer is C
