Pair of linear equations in two variables
highA pair of linear equations in two variables is two first-degree equations written together, such as ax + by + c = 0 and px + qy + r = 0, with the same two unknowns.
Always write both equations clearly first, then decide whether graphing, substitution, or elimination will be fastest for the given question.
Graphical representation of a pair of linear equations
highGraphical representation means drawing both linear equations on the same Cartesian plane and using their position to understand the solution.
Mark at least two correct points for each line, then draw a neat straight line through them on the same graph.
