The Excel Linest Function uses the least squares method to calculate the line of best fit through a supplied set of y- and x- values. If there is a single range of x-values, the calculated line satisfies the simple straight line equation:

I've used goal seek to solve equations, but it is not very useful when there are several possible solutions and one needs them all. I also have used trendlines in charts to find the equation for the line of best fit. Not quite the same as solving equations, but easier than running linear regressions to find the same result.

For our example, the linear regression equation takes the following shape: Umbrellas sold = b * rainfall + a. There exist a handful of different ways to find a and b.The three main methods to perform linear regression analysis in Excel are:

Intercept is a point on Y-axis where the line crosses. Or, we can say that it is the value of y when x is 0. How to find the y-intercept of a function? The formula for Intercept for a simple line connecting two points on the line is: b (intercept) = y- mx. where b is Intercept. y is y co-ordinate and x is x co-ordinate. m is the Slope of a line.

How do i find the equation of the line and R2? I don't have Excel 2008 handy to test, but usually one way is to right-click (or Control-click) the trendline, choose Format Trendline from the pop-up menu, click Options, click "Display equation on chart" and "Display R-squared value on chart," and click OK.

In this article, we will see how to solve it with Excel. To find intersection of two straight lines: First we need the equations of the two lines. Then, since at the point of intersection, the two equations will have the same values of x and y, we set the two equations equal to each other. This gives an equation that we can solve for x

All of those relationships can be described with linear equations. One of the most common and convenient forms of a linear equation is y = m*x +b, where m is the slope of the line and b is the y-intercept. If you've got data, but aren't sure how to put it in that linear form, Excel for the Mac can help.

In Correlation we study the linear correlation between two random variables x and y. We now look at the line in the xy plane that best fits the data (x 1, y 1), …, (x n, y n).. Recall that the equation for a straight line is y = bx + a, where b = the slope of the line a = y-intercept, i.e. the value of y where the line intersects with the y-axis. For our purposes we write the equation of the ...
