D. m= -1

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

i got -1/5

anonymous · Answer

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