# How to get y=mx+b on Excel

In our dataset, we have two sets of numerical values: X and Y. Our goal is to establish a linear equation of the form y=mx+c that best fits the relationship between X and Y. To achieve this, we will create a chart of the X and Y data points, and then apply a trend line to the chart that best fits the data. Finally, we will display the equation of the trend line on the chart.

“y=mx+b” is a mathematical formula for a linear equation, where “y” represents the dependent variable, “x” represents the independent variable, “m” represents the slope of the line, and “b” represents the y-intercept. In Excel, Finding the equation of a line in the form of “y=mx+b” is a fundamental tool in data analysis, modeling, and prediction, and has numerous applications in various fields.
