Nope! In order to solve this just plug in the points x and y values into the equation and if they're not equal then that point won't be on the line.

The scores of five students on a quiz are 11, 21, 16, 7, and 10. Find the mean and median of the scores.
photoshop1234 [79]
Hello!

The mean is the average. To calculate it you add up all the numbers, and divide by how many numbers there were. So for example, if you had 1 and 3, you would add them and divide by two since there were two numbers. We will calculate the mean of this data set below.

(11+21+16+7+10)=65
65/5=13

The mean of the data set is 13.
---------------------------------------------------------------------------------------
Now we need to find the median. To do so we have to first order all of the numbers from least to greatest.

7,10,11,16,21

Now we have to find the number in the middle of the data set.

11 is our median. (Note that when calculating the median with an even number of data points, you will find the mean of the two center numbers)

I hope this helps!

What is the inverse of the function g(x)=\dfrac{-x-2}{x+4}g(x)= ​x+4 ​ ​−x−2 ​​ g, left parenthesis, x, right parenthesis, equal
dybincka [34]
Hello :
y= (-x-2)/(x+4)
clculate : x 
y(x+4) = -x -2
yx +x = -2 - 4y
x(y+1) = - 2 -4y  
x = (- 2 -4y )/(y+1)
so : g-1(x) =  (-2-4x) / (x+1)
