Actually, two separate points are enough to determine the line.

How do you find the equation for the line of best fit?
There are many ways, but probably you aren't in a statistics class, but in an algebra class. Step 1 plot all the data points on a coordinate plane graph (x-y graph) Step 2 estimate a line 'close' to points. Step 3 use 2 points ON THE LINE (these do not need to be data points) Step 4 find slope of line using points from step 3 Step 5 use point-slope formula to write the equation.
What is the sum of all the data points divided by the number of data points?
the average
How do you write the equation for normal distribution data in excel?
y=(1/(sqrt(2*22/7)))*((e)power-((X squred)/2))
What fraction of the data is between 5 and 12?
(the number of data points between 5 and 12)/(the total number of data points)
What is the mean average of this data?
Add up all the values and divide by the number of data points.
How do you Write an equation in the form of y equals kx for the following data?
There are no "following" data!
A set of data points has an equation of equals -1.5 plus 2.5x?
-1.5

Why is a graph more informative than an equation?
A graph is more informative than an equation because a graph is easier to interpret visually, and find all the points and line them up, rather than just a slope which shows no points(data).
Why cant you just connect all the data points?
You could, but you need to decide what the point of doing so would be!
What is a sentence using the word graph?
The graph showed the results from his experiment. You can graph the data points to see what type of curve your equation defines.
How can you model data with a linear equation?
by figuring out the equation
What is the sum of all the data points divided by the number of data points?
the average
How do you get the last suit on odst?
you have to beet all misions on legendary. and you cant start at check points or else you loose your data.-SPARTAN2787 xbox live
What is the difference of average and media?
Average is the sum of all data points divided by the number of data points. Median is the data point that is exactly halfway between the lowest and highest data points.
How do you write the equation for normal distribution data in excel?
y=(1/(sqrt(2*22/7)))*((e)power-((X squred)/2))
When you extend a line beyond your data points to predict the value outside your data points you?
extrapolate
