Use the distance formula: D=sqrt((x2-x1)^2+(y2-y1)^2)
Plug in:
D=sqrt((9-8)^2+(-1-2)^2)
D=sqrt(1^2+(-3)^2)
D=sqrt(1+9)
D=sqrt(10)
So the distance is about 3.16 units
Hope this helped!
To check if an expression is indeed a function, you'd use the vertical line test, if it passes, then it IS a function.
now, if it passes the horizontal line test, doesn't mean much function wise, what the dickens is up with the horizontal line test anyway?
well, if the graph, does indeed pass the vertical line test first, is a function, IF then it also passes the horizontal line test, it means, is not only a function but a one-to-one function, meaning there's a unique x-coordinate value for every unique y-coordinate value.
note:
only one-to-one functions have an inverse expression that is also a function.

Step-by-step explanation:
The missing number in the given data that has a mean of 79 is: 60.
<h3>How to Find the mean of a Data?</h3>
The mean of a data set is simply the average, that is, it is the sum of all data values divided by the number of data values.
Let x represent the missing number in the data. If the mean is 79, we would have the following:
(89 + 74 + 92 + 80 + x)/5 = 79
(335 + x)/5 = 79
335 + x = 5(79)
335 + x = 395
x = 395 - 335
x = 60
Missing number is: 60.
