Question

The distance of point -6,8 from tge origin is ______ unit

Answer 1

Answer:

10cm

Step-by-step explanation:

There is a formula "distance formula" for finding distance or magnitude in the cartesian plane.

for point (x,y), dist. $d = \sqrt{x^2+y^2}$

for points (x1,y1) and (x2,y2), dist. $d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$

using the formulas, distance for (-6,8) is,

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