Answer:
When you have a equation such as
y = 2x + 4
This means, that whatever x equals, do the rest equation for y. They give you a table, the numbers under x, you replace x with the x in the equation. Multiply it next to the number. Do the rest of the equation, that is how you get y.
Once you do all x numbers, you have to graph it.
X = run
Y = rise
X is the horizontal line
Y is the vertical line

Look at the middle, the x numbers that are to the right of the vertical line are negative.
The ones to the left are positive.
The numbers that are on the top of y are positive
The numbers that are on the bottom are negative.

Answer:
(6, 8)
Step-by-step explanation:
I just drew the graph and measured the middle of the line.
Circumference of a circle:
C = 2 pi r
r = C / 2 pi
r = 37.68 / (2 * 3.14)
r = 6
Area of a circle:
A = pi r^2
A = 3.14 * 6^2
A = 113.04
Answer
The area of a circle = 113.04 square units
