Question 464024: This table shows 4 observations of a pair of variables (x, y). The variables x and y are positively correlated, with a correlation coefficient of 0.99. Find the slope, b, of the least squares regression line, y = ax + b, for these data.
x 1 2 3 4
y 1 3 7 10

You can put this solution on YOUR website! This table shows 4 observations of a pair of variables (x, y). The variables x and y are positively correlated, with a correlation coefficient of 0.99. Find the slope, a, of the least squares regression line, y = ax + b, for these data.
x 1 2 3 4
y 1 3 7 10

Note: Again, the points are not on a single line.

Linear Regression equation: y = 3.1x - 2.5
slope = a = 3.1
intercept = b = -2.5
