Answer:
The y-coordinate of a point is the value that tells you how far from the origin the point is on the vertical, or y-axis. To find the y-coordinate of a point on a graph:
Draw a straight line from the point directly to the y-axis.
The number where the line hits the axis is the value of the y-coordinate.
Looking back at the graph with our points B and D, we now identify the y-coordinate for each.
- The y-coordinate of point B is 400.
- The y-coordinate of point D is 100.
