Answer:

$\displaystyle y = -3x + 9$

Step-by-step explanation:

First, find the rate of change of the line:

$\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-6 + 3}{-1 + 2} = m \hookrightarrow \frac{-3}{1} = m \\ \\ \boxed{-3 = m}$

_______________________________________________

Now plug all the information into the Slope-Intercept Formula. It does not matter which ordered pair is chosen:

$\displaystyle 3 = -3[2] + b \hookrightarrow 3 = -6 + b; 9 = b \\ \\ \boxed{\boxed{y = -3x + 9}} \\ \\ OR \\ \\ 6 = -3[1] + b \hookrightarrow 6 = -3 + b; 9 = b \\ \\ \boxed{\boxed{y = -3x + 9}}$

I am joyous to assist you at any time.

I need to find Domain and Range but how do I know when to use brackets or parentheses

german

Answer:

Square brackets [ or ] are used when the end point is included.
Parentheses ( or ) are used when the end point is not included.

Step-by-step explanation:

The domain is the horizontal extent of the graph. Here, it is from -2 to +3, with -2 included in the domain and +3 not included.

As an inequality, the domain is written ...

-2 ≤ x < 3

In interval notation, we use a square bracket for the "or equal to" case:

[-2, 3)

The range is the vertical extent of the function. Here, the range extends from -4 (not included) to +5 (included).

As an inequality, the range is written ...

-4 < y ≤ 5

In interval notation, the range is written using a square bracket for the "or equal to" case:

(-4, 5]

Comment on infinity

There is no such thing as "equal to infinity" so an infinite limit is always represented in interval notation using a parenthesis.

I don’t know what to do on here it’s really hard and I need help for the answer

Alla [95]

Ok so our original fraction is:
$\frac{36 {x}^{12} }{6 {x}^{9} }$
To simplify this fraction, look for instances where the values on the top and bottom can be reduced:

For example, 36 over 6 is the same as 6 over 1, so we can simplify the fraction so it is:
$\frac{6 {x}^{12} }{ {x}^{9} }$
We can also eliminate the denominator by dividing the nominator by x^9 so:
$\frac{6 {x}^{12} }{ {x}^{9} } \div \frac{ {x}^{9} }{ {x}^{9} }$
$= 6 {x}^{3}$
And that is the simplified answer of the fraction

Hope this helped
