I have several tables of data and need to show symbolic 
representation and graphical representation 
For example:
14 15
16 13 I have several tables like this - don't understand
18 20
20 15
22 18
24 22
26 18
28 23 

To form the graph, plot the points and connect them



Now often you are asked to find the regression line
using a long formula.  This line is the line that
comes the closest to fitting the data given.  I will
not go through the required substitution here, but
I will just give the result and draw its graph:

The equation of the regression line is 

y = .5357x + 6.75

and you see its graph is the green line below
