Question

Write the ordered pair that represents YZ Then find the magnitude of YZ. Y (4,2) Z(2,8)

Answer 1

For the given points $Y(4,2)$ and $Z(2,8)$, we have to find the ordered pair that represents YZ.

YZ is calculated by finding the difference between the coordinates Z and Y.

So,

$YZ = Z- Y$

$YZ = (2,8)- (4,2)$

$YZ = (2-4,8-2)$

$YZ = (-2,6)$

Magnitude of coordinate (x,y) is calculated by the formula = $=\sqrt{x^{2}+y^{2}}$

Magnitude of YZ=$\sqrt{(-2)^{2}+(6)^{2}}$

= $\sqrt{4+36}$

$=\sqrt{40}$

$=2\sqrt{10}$ units.
