Remark
In this section, it's a very good idea to make yourself a formula page. Every time you answer a question, write down the formula you used. Usually the sample questions will do that for you. Follow them carefully.
<h3>Problem 6</h3><h3>Formula</h3>Key word: midpoint.
Formula
x1 = -6
x2 = 3
y1 = 1
y2 = - 2
<u>Solve</u>
midpoint = (- 6 + 3)/2 , (1 - 2)/2
midpoint = - 3/2, -1/2
Answer: D
Problem 7
Remark
I'm going to do no more than outline the answer. The formula is the same.
0,0 does not affect the outcome at all.
x1 = 4
y1 = 6
x2 = 0
y2 = 0
Midpoint = (4 + 0)/2, (6 + 0)/2
Midpoint = 4/2, 6/2
Midpoint = (2,3)
