Answer: $8.25 is your answer.
Step-by-step explanation:
12 x 3 = 36
2.75 for 12 so 2.75 times 3 = 8.25
The answer would be 0.19 if your have rounded it. Unrounded it is 0.1875
It is the origin of a graph; where the x-axis and y-axis intercept .
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
