What is the distance between (1, 3) and (5, 6)?(a) 3 units(b) 4 units(c) 5 units(d) 25 unitsThis question was posed to me during an interview.My enquiry is from Slope of a Line in section Straight Lines of Mathematics – Class 11

Answer»

Right OPTION is (c) 5 units

The explanation: We know, distance between two points (x1, y1) and (x2, y2) is\(\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\).

So, distance between (1, 3) and (5, 6) is \(\sqrt{(1-5)^2+(3-6)^2}=\sqrt{(4)^2+(3)^2}\) = 5 units.
