Q. Point Q is located at (−4,6). Point R is located at (8,6).What is the distance from point Q to point R ?
Identify Coordinates: Identify the coordinates of points Q and R. Point Q is at (−4,6) and Point R is at (8,6).
Recognize Same Y-coordinate: Recognize that the points share the same y-coordinate.Since both points have a y-coordinate of 6, they lie on a horizontal line.
Use Distance Formula: Use the distance formula for points on a horizontal line.The distance between two points on a horizontal line is the absolute difference between their x-coordinates.Distance = ∣x2−x1∣
Substitute X-coordinates: Substitute the x-coordinates of points Q and R into the distance formula.Distance = ∣8−(−4)∣
