Regression Line Equation. Our regression line is going to be y is equal to we figured out m. Y 173 51 4 83x y 173 51 4 83 x remember it is always important to plot a scatter diagram first.
This uncertainty differs from slope which is always interpretable. So we have the equation for our line. Sometimes the y intercept can be interpreted in a meaningful way and sometimes not.
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.
Y a bx. The y intercept is the place where the regression line y mx b crosses the y axis where x 0 and is denoted by b. Y is the dependent variable and plotted along the y axis. The slope of the line is b and a is the intercept the value of y when x 0.
