Final answer:
To draw a line through all points with a y-coordinate of 4, connect the points with a horizontal line parallel to the x-axis.
Step-by-step explanation:
To draw a line through all points with a y-coordinate of 4, we can visualize it on a graph. Since the y-coordinate is always 4, we can draw a horizontal line through all the points on the graph that have a y-coordinate of 4. This line will be parallel to the x-axis.
For example, if we have the points (2, 4) and (5, 4), we can connect these points with a straight line. This line represents all the points with a y-coordinate of 4.
Example:
Graphically, a line passing through points with a y-coordinate of 4 will look like:
