Question

If a is a point on y axis, whose ordinate is 3 and coordinate of point b is (-5,2), then find the distance ab

Answer 1

Step-by-step explanation:

A is a point on Y - axis with ordinate = 3

then co- ordinate of A = (0,3)

and B = (-5,2)

By distance formula,

AB = √[(-5-0)² + (2-3)²] = √(25+1) = √26

AB = √26 units
