Answer:

none of the lines are parallel or perpendicular to each other

Explanation:

which lines are parallel or perpendicular? line A:(-4,-1)(2,-2)line B:(-5,-3)(5,1) line C:(-2,-3)(2,-1)​

in order to know which lines are parallel or perpendicular, we need to find the slopes of the lines given

Slope M = y2-y1/x2-x1

For line A;

Ma = -2+1/2+4

Ma = -1/6

Slope of line A is -1/6

For line B;

Mb = 1 -(-3)/5-(-5)

Mb = 1+3/5+5

Mb = 4/10

Mb = 2/5

The slope pf line B is 2/5

For line C;

Mc = -1-(-3)/2-(-2)

Mc = -1+3/2+2

Mc = 2/4

Mc = 1/2

Hence the slope of line C is 1/2

Since all the slopes are different , hence none of the lines are parallel or perpendicular
