Question

Calculate the distance between the points A (-3, 1) and B on
Y-axis whose ordinate is 5.

Answer 1

Answer:

IT'S GIVEN, A = (-3,1)

B = (0,5)

DISTANCE B/W 2 POINTS =

$\sqrt{x2 - x1) {}^{2} + (y2 - y1) {}^{2} }$

$= \sqrt{(0 + 3) {}^{2} + (5 - 1) {}^{2} }$

$= \sqrt{9 + 16}$

$= \sqrt{25}$

$= 5.$
