Question
The coordinates of a point A is (3, 5). A line perpendicular to x–axis passes through point A. Find the length of the line segment from x–axis to A.
Solution
The length of the line segment from the x-axis to point A is simply the y-coordinate of point A. This is because the line segment is perpendicular to the x-axis and therefore runs parallel to the y-axis. The length of this line segment represents a vertical distance on the coordinate plane.
So, for point A which is (3, 5), the length of the line segment from the x-axis to A is 5 units.
