How many lines can pass through a single given point in the coordinate plane?

Class 9Linear Equations in Two VariablesLinear Equations
  • AExactly one
  • BExactly two
  • CInfinitely many
  • DNone

Step-by-Step Solution

Through one point infinitely many lines can be drawn; correspondingly there are infinitely many linear equations whose graphs pass through it.
Answer: C) Infinitely many

Key idea: Graphing a linear equation

Three steps:

1. Find at least **two solutions** (preferably the and intercepts — easiest to plot).
2. Plot those points on the coordinate plane.
3. Draw a straight line through them.

Every linear equation in two variables graphs as a STRAIGHT LINE. (That's why they're called 'linear'.)

For accuracy: find a third solution and verify it lies on the line — catches arithmetic mistakes.
