Answer:
Mean: 4.44 add up every number and divide it by how many there is.
Median: 3 put from least to greatest and count till the middle.
Mode: 3 because it appears the most
Answer:
The equation is 
Step-by-step explanation:
If we want a line parallel to the line in the problem it will have the same slope. The equation given in the problem is already in slope intercept form so we can take the slope for the new equation directly from this equation.
The slope-intercept form of a linear equation is: 
Where m is the slope and b is the y-intercept value.

Therefore the slope is

We can now use the point-slope formula to write the equation of the parallel line:
The point-slope formula states:

Where m is the slope and
is a point the line passes through.
Substituting the information from the problem gives:


Or, we can solve for y to put the equation in slope-intercept form:




Step-by-step explanation:
So for this question just substitute the value and work out. I thought it it to the power of 2 as I can't tell from the question.
