Question

Line AB formed by (-4,7) and (-2,6)Line CD formed by (2,-2) and (-8,3)Parallel perpendicular or neither

Answer 1

For this question, we compute the slope of each line. To compute the slope of the lines we use the following formula:

`m=(y_1-y_2)/(x_1-x_2)`

Line AB:

`m_(AB)=(7-6)/(-4+2)=(1)/(-2)=-(1)/(2)`

Line CD:

`m_(CD)=(-2-3)/(2+8)=(-5)/(10)=-(1)/(2)`

Therefore we conclude that lines AB and CD are parallel.
