Answer:
The lines are parallel
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
Remember that
If two lines are parallel, then their slopes are the same
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
step 1
Find the slope JK
we have
substitute the values
step 2
Find the slope LM
we have
substitute the values
step 3
Compare the slopes
so
therefore
The lines are parallel
