Q68.Slope of a line passing through P(2, 3) and intersecting the line x + y = 7 at a distance of 4 units from P, is (1) √7−1 (2) 1–√7 √7+1 1+√7 (3) √5−1 (4) 1–√5 √5+1 1+√5

What This Question Tests

This problem uses the concept of the parametric form of a straight line. By representing a point at a given distance from P on the line, and then substituting its coordinates into the equation of the intersecting line, the slope of the line can be determined.
