we know that
Correlation is a term that is a measure of the strength of a linear relationship between two quantitative variables
Positive correlation is a relationship between two variables in which both variables move in the same direction and negative correlation is a relationship between two variables in which one variable increases as the other decreases, and vice versa
steps you take to find equation for the line that fits best
step 1
draw the line that fits best
step 2
take two points from the graph
step 3
Find out the slope
step 4
with the slope and one point, calculate the equation of the line in slope intercept form
y=mx+b
