Question

What is the distance of the point P(-6,8) from the origin ?

Answer 1

Since we have to measure distance from origin:-

x1 = - 6

x2= 0

y1 = 8

y2 = 0

Distance between two points =

$\sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } \\ \\ = \sqrt{ {(0 - ( - 6)}^{2} + {(0 - 8)}^{2} } \\ \\ = \sqrt{36 + 64} \\ \\ = \sqrt{100} \\ \\ = 10 \: unit$

Hope it helps.
