in the blanks below. Find the slope of the line passing through the points (-9, 2) and (9,2). slope: ​
user100 [1]

I will assume that we are trying to find the slope between (-9,2) and (9, 2)

The slope's equation ⇒  \frac{y2-y1}{x2-x1}

<u>Let's set the variables</u>:

   (x1, y1) --> (-9, 2)

   (x2, y2) --> (9, 2)

<u>Now let's plug them in:</u>

  Slope = \frac{2-2}{9--9} =\frac{0}{18} =0

<u>Thus the slope of the line is 0.</u>

Hope that helps!

Llana [10]

Answer:

The standard deviation is 10.38

Paulo’s grandfather gave him a collection of 20 coins. Each month Paulo adds 4 coins to his collection. Which inequality can be
Phoenix [80]

Answer:

4m+20>50

Step-by-step explanation:

Let <em>m</em> represent the amount of months that has passed.

Paulo started out with 20 coins.

Each month, he adds four more coins to his collection.

Therefore, the amount of coins added after <em>m</em> months will be given by 4<em>m</em>.

So, the amount of coins Paulo has total after <em>m</em> months can be given by:

4m+20

We want to know when Paulo will have "more than" 50 coins in his collection. Therefore, we will use the "greater than" sign. Thus, our inequality will be:

4m+20>50
