I will assume that we are trying to find the slope between (-9,2) and (9, 2)
The slope's equation ⇒ 
<u>Let's set the variables</u>:
(x1, y1) --> (-9, 2)
(x2, y2) --> (9, 2)
<u>Now let's plug them in:</u>

<u>Thus the slope of the line is 0.</u>
Hope that helps!
I'm not 100% sure I'm just trying to help. I've seen this question before and I believe the answer was <span>362,880, but that seems like an a full lot to me personally, but like I said just trying to help. :)</span>
Answer:
1530
Step-by-step explanation:
I believe that is the answer
u just divide the 3rd column by 3 thats how I did it
hope this helped :)
Answer:
x=3
Step-by-step explanation:
Since they are similar triangles, we can use ratios to solve
x 3.5
----- = -------
6 7
Using cross products
7x = 21
Divide each side by 7
7x/7 = 21/7
x = 3
