Point Q is located at (-4, 6). Point R is located at (8, 6).
Bess [88]

Step-by-step explanation:

Hi there!

Given;

Point Q is located at (-4, 6). Point R is located at (8, 6).

Note: Use distance formula.

Now;

(d) =  \sqrt{( {x2 - x1)}^{2}  + ( {y2 - y1)}^{2} }

Keep all values;

(d) =  \sqrt{ {(8 + 4)}^{2} + ( {6 - 6)}^{2}  }

Simplify;

(d) =  \sqrt{( {12)}^{2} }

Therefore, the distance is 12 units.

<u>Hope</u><u> it</u><u> helps</u><u>!</u>
