Question

if the intercept on Y- axis and the slope of a regression line are 4 and 3 respectively, then the equation of the regression line can be written as ?

Answer 1

Answer:

The formula for the best-fitting line (or regression line) is y = mx + b, where m is the slope of the line and b is the y-intercept. This equation itself is the same one used to find a line in algebra; but remember, in statistics the points don’t lie perfectly on a line — the line is a model around which the data lie if a strong linear pattern exists.

The slope of a line is the change in Y over the change in X. For example, a slope of

means as the x-value increases (moves right) by 3 units, the y-value moves up by 10 units on average.
