Answer:
1. *2/multiplied by 2, since each number gets higher by *2.
2. *3/multiplied by 3, since each number gets higher by *3
3. ÷2/divided by 2, since each number gets lower by ÷2.
Express it as a decimal.
3/20 = 0.15 by division
then move the decimal point twice to the right and affix the percent symbol
thus, 15%.
6 unless it talks about positive to negative then its 2
The fourth vertex would be at point (-9,1).
The slope from (5,-4) to (3,4) is -8/2 or -4.
So I did that with (-7,-7) to the fourth vertex to get the answer.
