Answer:
|QR|=12
Step-by-step explanation:
The point Q is located at (-4,6) and the point R is located at (8,6).
We want to find the distance from point Q to point R.
Since the y-coordinates of the two points are the same, we can use the absolute value method.
According to this method; the distance from point Q to point R is just the absolute value of the difference in the x-values.
|QR|=|8--4|=12
