Question

-) Distance of point (-6, 8) from the origin is....
A) 14
B) 2
C) 10
D) -5
​

Answer 1

Solution

coordinates of origin is=(0,0)

now the distance between the points (0,0)&(-6,8) is

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

Hope this helps you......
