Mind Map for CBSE Class 10 Maths Chapter 2 – Pair of Linear Equations in Two Variables
Major topics discussed in CBSE Class 10 Maths Chapter – Pair of Linear Equations in Two Variables include:
1. A pair of linear equations in two variables can be represented, and solved, by the:
(i) graphical method
(ii) algebraic method
2. Graphical Method: 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. In this case, the pair of equations is consistent.
(ii) If the lines coincide, then there are infinitely many solutions — each point on the line being a solution. In this case, the pair of equations is dependent (consistent).
(iii) If the lines are parallel, then the pair of equations has no solution. In this case, the pair of equations is inconsistent.
3. Algebraic Methods: Two methods for finding the solution(s) of a pair of linear equations involve:
(i) Substitution Method
(ii) Elimination Method
4. If a pair of linear equations is given by a1x + b1y + c1 = 0 and a2x + b2y + c2 = 0, then the following situations can arise:
(i) a1/a2 ≠ b1/b2 : In this case, the pair of linear equations is consistent.
(ii) a1/a2 = b1/b2 ≠ c1/c2 : In this case, the pair of linear equations is inconsistent.
(iii) a1/a2 = b1/b2 = c1/c2 : In this case, the pair of linear equations is dependent and consistent.
