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
8/10 > 3/4 > -3/4 > -7/10
<h3><u>Write two division expression s that have the same vaule as 36.8 ÷ 2.3
</u></h3>

<em><u>Solution:</u></em>
Given that,
We hve to find the two division expression s that have the same vaule as 36.8 ÷ 2.3
From given,

So, we have to find two division expressions that has a value of 16
<em><u>First division expression</u></em>
We know that 32 divided by 2 gives 16
Thus, we can write as,

<em><u>Second Expression:</u></em>
We know that 48 divided by 3 gives 16
Thus, we can write as,

Thus the two expressions are found
it's 18 with a remainder of 13. I attached a photo that shows the work of it
