Answer:
The slope of line MN is two thirds,
The slope of line RS is negative three-halves
and line RS is perpendicular to both line MN and PQ
Step-by-step explanation:
For the first two, I found the slope using the slope formula, and I know the third one is correct because that is what it says in the very beginning.
Hope this helped, sorry if it is a little hard to understand, it was pretty hard to understand. :)

Step-by-step explanation:
<h3>The number of beads lina has is 31</h3><h3>
Laura made a mistake by adding the constant 7 and variable 4b</h3>
<em><u>Solution:</u></em>
Given that,
Laura wrote and solved the following expression to find the total number of beads Lina has
There are 6 beads in each packet
7+4b = 11b
= 11(6)
=66
From given,
Lina has a total of 7 + 4b beads
Given that, There are 6 beads in each packet
Substitute b = 6
7 + 4(6)
Simplify
7 + 24
Add
31
Thus, she has a total of 31 beads and not 66 beads
Laura made a mistake by adding the constant 7 and variable 4b
But a constant and variable cannot be added
Both missing angles are 45°
A heptagon has 7 sides.
Sum of all interior angles = (7 - 2) x 180 = 900°
900 - 776 = 124°
Answer: The final angle must be 124°
