X=1, and 3/8 it is a mixed number.
I'm guessing the repeating part is 89 at the end, so that

Answer:
What are the Answer Choices
Step-by-step explanation:
Answer:
-1/6
Step-by-step explanation:
Slope=change in y/change in x
Y-values: 8 and -4
X-values: 4 and 2
Change is the difference in position (subtract)
8- (-4)/(4-2)=12/2=6 = first slope
Perpendicular lines have opposite reciprocal slope
