How do you find the distance between two points that have the same y-coordinate and lie in the same quadrant?

To find the distance between two points that have the same y-coordinate and lie in the same quadrant, you simply subtract their x-coordinates. Since the y-coordinates are the same, the distance formula simplifies to the absolute difference of the x-coordinates: ( \text{Distance} = |x_2 - x_1| ). This will give you the horizontal distance between the two points.
