9. 5y
10. 102 square-4
11. 2a5 square +5b
12. 8m+2+4n
Y=2x or y=x+2 If you plug in the ordered pairs for both, they fit.
Answer:
B
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to

<u>Part a) Find the slope of line PQ</u>

substitute in the formula


Any line parallel to X-axis has slope equal to zero
so
the line PQ is parallel to the x-axis
therefore
<u>the answer Part a) is </u>

<u>Part b) Find the slope of line MN</u>

substitute in the formula


Anything divided by zero is undefined
m=undefined
therefore
<u>the answer Part b) is </u>
undefined
<u>Part c) How are the two lines related ? </u>
we know that
Any line perpendicular to X-axis has slope undefined
Because the term
will always be zero
so
<u>the answer Part c) is</u>
the lines are perpendicular
Answer:
I don't know what you are saying for solve for x though if your saying simplify
