Question

Describe how a points location changes after you add a negative value to the y coordinate of an ordered pair and leave the x coordinate the same.

Answer 1

Adding a negative value to the y coordinate of a point while keeping the x coordinate the same moves the point downwards along the y-axis without affecting its horizontal position.

Step-by-step explanation:

When adding a negative value to the y coordinate of an ordered pair while keeping the x coordinate the same, the point's location on a graph changes vertically. The negative value effectively moves the point downwards along the y-axis. If the original point is represented by the coordinates (x, y), after adding a negative value ‘a’, the new location of the point becomes (x, y-a). This downward shift does not affect the x coordinate and, therefore, there is no horizontal movement. For example, if we have a point at (3, 4) and we add -2 to the y coordinate, the new position of the point will be (3, 2), which is two units lower on the graph.

Answer 2

A points location will change after you add a negative value to the y coordinate even if you leave the x coordinate the name because you are changing the value of the y coordinate. For example, if you have (4,6) as a coordinate and then change it to (4,-6), the coordinate will now just be on the other side of the x axis
