Q1 of 84 Page 114

Find the distance between the following pairs of points.

(0, 17) and (0, −1)

Formula used:


(0, 17) and (0, –1)


x1 = 0 and x2 = 0


y1 = 17 and y2 = –1


⇒ D = √ ((0 – 0)2 + (–1 – 17)2)


⇒ D = √ ((0)2 + (–18)2)


⇒ D = √ (0 + 324)


⇒ D = √ 324


⇒ D = √ (18 × 18)


⇒ D = 18
