Question 4 of 10
Assertion (A): The equation of the line making intercepts \( 2 \) and \( 3 \) on the x-axis and y-axis respectively is \( 3x + 2y = 6 \).

Reason (R): The equation of a line making intercepts \( a \) and \( b \) on the x- and y-axes respectively is given by the intercept form \( \frac{x}{a} + \frac{y}{b} = 1 \).

Question 7 of 10
Assertion: The three lamp posts located at \((1,1)\), \((3,5)\) and \((5,9)\) lie on one straight road.
Reason: If the distances between every pair of three points are equal, then the three points are collinear.

Question 10 of 10
Assertion (A): The line passing through \( (2, 3) \) and \( (4, 5) \) is perpendicular to the line passing through \( (3, 4) \) and \( (5, 2) \).

Reason (R): Two non-vertical lines are perpendicular to each other if and only if the product of their slopes is \( 1 \) (i.e., \( m_1 m_2 = 1 \)).
