Question 9 The distance of the point P (3, −4) from the origin is (a) 7 units (b) 5 units (c) 4 units (d) 3 units We need to find distance between point P(3, –4) and Origin O (0, 0) Now, Required Distance = √((𝑥_2−𝑥_1 )^2+(𝑦_2−𝑦_1 )^2 ) = √((0−3)^2+(0−(−4))^2 ) = √((−3)^2+(4)^2 ) = √(3^2+4^2 ) = √(9+16) = √25 = 5 Therefore, Required Distance = 5 units So, (b) is the correct answer
