const (optional) is a boolean value specifying whether to force the parameter b (intercept) to equal 0:.If known_x's is omitted, it is assumed to be the array that is the same size as known_y's. known_x's (optional) are independent data values.known_y's (required) are dependent data values,.To calculate the linear trendline values, Excel offers the array function TREND () (see the notes above about array functions) that returns values along a linear trend: If the count of known_y's is different from known_x's, the INTERCEPT () and SLOPE () functions returns #N/A.If there is only one value in known_y's or known_x's, the INTERCEPT () and SLOPE () functions will return #DIV/0!.The SLOPE () function returns the slope (the parameter a) of a linear regression line based on known_y's and known_x's data: known_x's (required) are independent data values (see an example below) - a range or array of numeric values.known_y's (required) are dependent data values - a range or array of numeric values,.In other words, using the known_x's and known_y's data, it returns the value y of the function for x = 0:

The INTERCEPT () function calculates the y value at which the linear trendline crosses the y-axis. Change the name of the axes and chart title.Excel offers the following functions to calculate trendline parameters: It will display the chart on the screen.Here, you will find different styles of the scatter chart.Now click on Insert Scatter(X, Y) or Bubble Chart.

Click on the Insert Tab and go to Charts group.

Select the value of both the columns you want to plot.

Place the independent variable on the left column and the dependent variable on the right column.

Open the worksheet containing the data that you want to plot on the Scatter chart.

To create a scatter chart on an Excel sheet, follow the steps below: The relationship between them is then represented by the graph line The independent variable is usually displayed on the chart's horizontal axis, while you can find the dependent variable on its vertical axis. The scatter plot presents the relationship between two variables along the two axes of the chart, with one variable independent and the other dependent.
