Find Slope for Line m:
----------------------------------------------------------------------------------------------------
Two points on the graph: (-4. 3) and (0,-4)

$\text {Slope = } \dfrac{3- (-4)}{-4 - 0} = -\dfrac{7}{4}$

----------------------------------------------------------------------------------------------------
Find Slope for Line n:
----------------------------------------------------------------------------------------------------
Two points on the graph: (1, 2) and (3, -2)

$\text {Slope = } \dfrac{2 - (-2)}{1-3} = -\dfrac{4}{2} = -2$

----------------------------------------------------------------------------------------------------
Find Slope for Line k:
----------------------------------------------------------------------------------------------------
Two points on the graph: ( -3 , -3) (4 , 1)

$\text {Slope = } \dfrac{1 - (-3)}{4 - (-3)} = \dfrac{4}{7}$

----------------------------------------------------------------------------------------------------
Answer: Since M and N do not have the same slope, they are not parallel.

Answer: The slope of K is the negative reciprocal of M, therefore they are perpendicular.

Let's do these in steps. Remember to show your work

#1. Convert into a improper fraction.

3 x 2 x 1 over 2cm.

#2. Simplify 3 x 2 to 6.

6 + 1 over 2cm.

#3. Change 6+1 to 7.

7 over 2m.

We finally get 7 over 2, but that rounded would be 7. So B would be our answer.
