In Graphical Method we will be drawing graphs of two equations and intersection point is called the solution of the graph. We all know that a graphical representation of a linear equation in two ...

The graph of a pair of linear equations in two variables is represented by two lines. (i) If the lines intersect at a point, then that point gives the unique solution of the two equations.

Pair of Linear ... Step 2: Substitute this value of y in the other equation, and reduce it to an equation in one variable, i.e., in terms of x, which can be solved. Sometimes, as in Examples ...

Linear relationships can be expressed either in a graphical format where the variable ... two individual points (x 1, y 1) and (x 2, y 2) as: There are three sets of necessary criteria an equation ...

It fits a straight-line equation to data points ... about one variable based on the information that is known about another variable. Linear regression can only be used when one has two continuous ...
