You could have ANY rule you want. Just substitute for and for but MAKE SURE THAT ONCE YOU SIMPLIFY IT, IT IS TRUE. Lets start making some equations!

How about:

If we substitute into it, we find it works.

How about:

By the way, if you substitute y and x into the equation above, you will find they also work.

Thank you, and I hope this helped.

Answer:

The circumference of the cookie is 37.68 inches.

Step-by-step explanation:

We have,

The area of a cookie is 113.04 square inches.

It is circular in shape. The area of circle is given by :

$A=\pi r^2$

r is radius of circle

$r=\sqrt{\dfrac{A}{\pi}} \\\\r=\sqrt{\dfrac{113.04}{3.14}} \\\\r=6\ \text{inch}$

The circumference of circular shaped object is given by :

$C=2\pi r\\\\C=2\times 3.14\times 6\\\\C=37.68\ \text{inch}$

So, the circumference of the cookie is 37.68 inches.

A line contains the two points plotted in the coordinate plane below.

Answer:

The slope would be 3.

Step-by-step explanation:

The formula for finding slope is $\frac{y1-y2}{x1-x2}$
We can plug these numbers into the equation by doing $\frac{1--5}{2-0}$
1--5 is equal to 1+5, which is 6.
2-0 is equal to 2.
$\frac{6}{2}$ is 3, which is how you get your answer.
I hope this helps! :)
