About Class 9 Maths Chapter 4 Linear Equations in Two Variables In this chapter, you will get to learn about linear equations and their applications in real life problems.

Linear regression attempts to estimate a line that best fits the data (a line of best fit) and the equation of that line results in the regression equation.

A linear equation is drawn as a straight line on a set of axes. To draw the graph we need coordinates. We generate these coordinates by substituting values into the linear equation.

The line of best fit is an output of regression analysis that represents the relationship between two or more variables in a dataset.
