how to find slope of regression line equation Use this Linear Regression Calculator to find out the equation of the regression line along with the linear correlation coefficient It also produces the scatter plot with the line of best fit
Linear regression line equation is written in the form y a bx where x is Independent Variable Plotted along X axis y is Dependent Variable Plotted along Y axis The slope of the regression line is b and the intercept Equation 10 2 1 is called the Sum of Squared Errors SSE Using calculus you can determine the values of a and b that make the SSE a minimum When you make the SSE

For your line pick two convenient points and use them to find the slope of the line Find the y intercept of the line by extending your line so it crosses the y axis Using the slopes and the y intercepts write your Scroll down to learn what the linear regression model is what the linear regression definition looks like and how to calculate the linear regression formula by hand You will also find an example of linear regression and a
Divide the change in y by the change in x to obtain the slope of the regression line Using the previous example yields 9 6 1 5 Note that the slope is positive which means the line rises as the y axis values increase By examining the equation of a line you quickly can discern its slope and y intercept where the line crosses the y axis The slope is positive 5 When x increases by 1 y increases by 5 The
