Question

3) Find the distance between the points P(-1.1) and Q(5,-7)​

Answer 1

Answer:

10

Step-by-step explanation:

Distance between two points =

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

here (x1 , y1) = (–1,1) and

(x2 ,y2) = (5,–7)

So we have

$= \sqrt{ {(5 - ( - 1))}^{2} + {( - 7 - 1)}^{2} }$

$= \sqrt{ {6}^{2} + {( - 8)}^{2} }$

$= \sqrt{36 + 64}$

$= \sqrt{100}$

$= 10$
