Question

1.Verifying the conditions of consistency/inconsistency for different pairs of linear equations in two variables using the graphical method.
2.Obtaining the solution of the corresponding quadratic equation (x2 + 4x = 60) by completing the square geometrically.​

Answer 1

Hii

To verify the conditions for consistency of a system of linear equations in two variables by graphical representation. An equation of the form ax+by+c = 0, where a, b, c are real numbers, a≠0, b≠0 and x, y are variables; is called a linear equation in two variables
