Answer:

Hi there, you can use Pitagoras relationship to solve this up (Without using any other "tool".

Point A is located wheter in (-6,8) or could be located in (-6,8)

Step-by-step explanation:

Point A is 10 units away from the origin, and its x coordinate is -6, using this information, you can draw a triangle from 0 to -6 (the basis) and using 10 as the hypotenuse, so, you have this equation:

$H^{2} = x^{2} +y^{2}$

solving for Y variable, you have this

y=± $\sqrt{10^{2}-(-6)^{2} }$

Note the combined sing ±, meaning that y=8 is a valid answer and that y= -8 is also a valid answer.

Hope It helps
