Question

Point Q is located at (-4, 6) Point R is located at (8, 6) What is the distance from point Q to point R?

Answer 1

$\text {Distance = } \sqrt{(Y2-Y1)^2+ (X2-X1)^2}$

$\text {Distance = } \sqrt{(6-6)^2+ (8+4)^2}$

$\text {Distance = } \sqrt{12^2}$

$\text {Distance = } 12 \text { units}$
 
Answer: Distance between QR = 12 units.

Answer 2

$\sqrt{ (8+4)^{2}+ (6-6)^{2} }$
                             ↓
$\sqrt{ 12^{2}+ 0^{2} }$
                      ↓
$\sqrt{144+0}$
           ↓
$\sqrt{144}$
         ↓
12
The distance between Points $Q$ and $R$ is 12 units.
Have a nice day!
