Math Problem Statement

Assertion: There are infinite number of lines which passes through (3, 2). Reason: A linear equation in two variables has infinitely many solutions.

Solution

Let's analyze the assertion and the reason to determine their correctness and the relationship between them.

Assertion:

There are infinite number of lines which pass through (3, 2).

  • This is true. A point on a plane can be part of infinitely many lines because you can draw a line in any direction that passes through that point. For example, lines with equations like y=mx+cy = mx + c, where c=23mc = 2 - 3m and mm is any real number, will pass through the point (3, 2).

Reason:

A linear equation in two variables has infinitely many solutions.

  • This is also true. A linear equation in two variables (like ax+by=cax + by = c) represents a line in the Cartesian plane, and all the points (solutions) on that line satisfy the equation. Since a line contains infinitely many points, the equation has infinitely many solutions.

Checking the relationship between Assertion and Reason:

  • The assertion and the reason are both true, but the reason does not directly explain the assertion. The reason talks about the solutions of a linear equation, while the assertion is about the number of lines passing through a given point. The reason could be misleading if interpreted as the explanation for why there are infinitely many lines through a single point.

Conclusion:

  • Assertion is true.
  • Reason is true.
  • Reason is not the correct explanation for the assertion.
