Question

Determine if JK and LM are parallel, perpendicular,or neither . HELP AND PLS SHOW WORK !!

Answer 1

1 - Perpendicular.

2 - Neither.

Explanation:

Use the slop formula to find the slope of the two sides.

`m = (y_(2)-y_(1) )/(x_(2)-x_(1) )`

`JK = (4-9)/(7-1) = (-5)/(6)`

`LM = (1-13)/(-2-8) = (-12)/(-10) = (6)/(5)`

Perpendicular - because a line that is perpendicular to another must have a slope that is the negative reciprocal of the first line.

`JK = (6-(-5))/(2-13) = (11)/(-11) = 1`

`LM = (-2-(-5))/(-4-(-1)) = (3)/(-3) = -1`

Not Parallel. Nor perpendicular.

Answer 2

1) not parallel

2)not parallel

Explanation:

fist one intersect already

and second one will eventually intersect
