Ya want to rationalize the denomenator
if we mutliply the whole thing by (√41)/(√41), we wil still have a √ there messing things up
we need to remember the difference of 2 perfect squares
remember
(a+b)(a-b)=a²-b²
so, we can see the denomenator is 5+√41
multiply the whole fraction by
we get

<em>It represents the charge per number of text messages sent in a month.</em>
<h2>Explanation:</h2>In this problem, we have the following equation:
We are said that:
C: Represents a cell phone company’s monthly charge for a text messaging service.
x: Represents the number of text messages per month.
So we can write our equation in Slope intercept form:
Where:
So the best interpretation of the slope is:
<em>It represents the charge per number of text messages sent in a month.</em>
