In order to graph it easily, we write the given equation into its slope intercept form which is expressed as:

y = mx + b

where m is the slope and b is the y-intercept.

<span>X+3y=9
(3y = 9 - X)1/3
y = (-1/3)X + 3</span>

Well, in order to first determine the slope or y-intercept, you must put change the equation to this format: y=mx+b.
m=slope and b=y-interceptI
in order to do that, you must change this equation.

x+3y=9
-x -x
----------
3y=9-x

Then, rewrite it as:

3y=-x+9
_______
3 3

simplify to

y=-x/3 +9

Please Hurry ...Which expression is equivalent to

Answer:

$\huge\boxed{\sf \frac{160rs^5}{t^6}}$

Step-by-step explanation:

$\sf 5r^6t^4 ( \frac{4r^3s^tt^4}{2r^4st^6} ) ^5$

Using rule of exponents $\sf a^m/a^n = a^{m-n}$

$\sf 5r^6t^4 ( 2 r^{3-4} s^{2-1}t^{4-6})^5\\5r^6t^4(2r^{-1}st^{-2})^5\\5r^6t^4 * 32 r^{-5}s^5t^{-10}$

Using rule of exponents $\sf a^m*a^n = a^{m+n}$

$\sf 160 r^{6-5}s^5t^{4-10}$

$\sf 160 rs^5 t^{-6}$

To equalize the negative sign, we'll move t to the denominator

$\sf \frac{160rs^5}{t^6}$

You can only divide a numerator and denominator one time when finding the simplest form.

False. Its as many times until you can no longer divide
