Final Answer:
The coordinates of point L are (x+3, y), where (x, y) are the coordinates of point K.
Step-by-step explanation:
In the Cartesian coordinate system, a point is represented by an ordered pair (x, y). When we say point K has coordinates (x, y), it means its horizontal position is x units and its vertical position is y units. To find the coordinates of point L, which is 3 units to the right of point K, we need to add 3 to the x-coordinate of point K. Therefore, the x-coordinate of point L is x+3, and the y-coordinate remains the same.
In mathematical terms, if point K has coordinates (x, y), then point L will have coordinates (x+3, y). This is because moving to the right on the coordinate plane involves increasing the x-coordinate.
So, when we add 3 to the x-coordinate of point K, we get the new x-coordinate for point L. The y-coordinate remains unchanged because the points have the same vertical position. This understanding of the Cartesian coordinate system helps us locate and describe the positions of points in a two-dimensional space.
