Graph equations in excel are easy to plot and this tutorial will walk all levels of excel users through the process of showing line equation and adding it to a graph. The slope and intercept values can also be obtained separately by using the corresponding function or by nesting the LINEST formula into INDEX. Extract the y-intercept value from the equation displayed on the graph.
There are multiple equations in the drop-down list then scroll down and select one of them to meet your actual needs.
Y dependent variable b the slope of the regression line. The mathematical formula for calculating the slope of known xs and know ys is Where x bar is the mean of the know xs and y bar is the mean of known ys. The slope and intercept values can also be obtained separately by using the corresponding function or by nesting the LINEST formula into INDEX. Suppose I have a table of data with x and y values.
