Given:
The vertices of the rectangle ABCD are A(0,1), B(2,4), C(6,0), D(4,-3).
To find:
The area of the rectangle.
Solution:
Distance formula:

Using the distance formula, we get




Similarly,





Now, the length of the rectangle is
and the width of the rectangle is
. So, the area of the rectangle is:




Therefore, the area of the rectangle is 20 square units.

Answer:</h2>
There are 2 ways to solve this system: by elimination or by graphing. I will solve it by elimination. First will solve for x.

Now we will solve for y using what we got for x.

Solution:
A: 
Well... looking at how to question is defining things.....i think this is a multiple choice question.....
Given:
"y" represents the population
"x" represents the number of years
duration = 2000 - 1990 = 10 years
population increase = 2700 - 1200 = 1500
Now,
<u></u><u>It says linear equation........</u><u>, So, we have to assume that every ten years the population increases by a fixed </u><u>amount that is 1500 people every 10 years.</u><u />
Now,
Every 10 years, the population increases by 1500
Every 1 year , the population increases by 1500 / 10
= 150
Now,
The equation in determining the population is:
y = 150x + 1200
