#### How to get equation of line in excel

## How do you calculate the equation of a line?

The general equation of a straight line is y = m x + c , where is the gradient and the coordinates of the y-intercept.

## How do you find the line of best fit on Excel?

Right Click on any one of the data points and a dialog box will appear. Click “Add Trendline”; this is what Excel calls a “best fit line”: 16. An options window appears and to ask what type of Trend/Regression type you want.

## What is the Y intercept formula?

The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.

## How do you graph a line from an equation?

To graph a linear equation, we can use the slope and y-intercept.Locate the y-intercept on the graph and plot the point.From this point, use the slope to find a second point and plot it.Draw the line that connects the two points.

## How do I plot data in Excel?

Title your graph.Enter your data into Excel. Choose one of nine graph and chart options to create. Highlight your data and ‘Insert’ your desired graph. Switch the data on each axis, if necessary. Adjust your data’s layout and colors. Change the size of your chart’s legend and axis labels.

## How do you use e in Excel?

Excel has an exponential function and a natural log function. The function is =EXP(value) and it gives the result of evalue (this is called syntax). For example, to find the value of e , we can write =EXP(1). Further if we put a number x in A1 and in A2 we put the formula =EXP(A1^2-1), this gives us ex2−1 .

## What is the Y intercept of y =- 2x?

Using the slope-intercept form, the y-intercept is 0 .

## How do I find slope and y intercept?

Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.
