This relation is a function because a function, in fact this is a linear function. We have that:
![\left[\begin{array}{cc}x & y\\2 & 3\\4 & 4\\6 & 5\\8 & 6\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7Dx%20%26%20y%5C%5C2%20%26%203%5C%5C4%20%26%204%5C%5C6%20%26%205%5C%5C8%20%26%206%5Cend%7Barray%7D%5Cright%5D)
As you can see below, all the points have been plotted an this is a linear function. Therefore, with two points we can get the equation, so:
Finally, the equation is:
Answer:
The top right graph.
Step-by-step explanation:
If you find the mean for all the graphs you get:
Graph 1: 7 Graph 2: 2
Graph 2: 7 Graph 4: 7
To find the mean you all all the numbers up and divide it by the number of data points for example heres the first graph:
8 + 8 +8 +8 +8 +8 +1 = 49 Add the data points
49 / 7 = 7 Divide by the total amount of points which is seven
It seems like it would make most sense to use a chef's hat on a catering business's business card as a logo.
