Final answer:
The student's question involves plotting the points (1,8) and (5,8) on a graph which represents a horizontal line at y = 8. No simplification is needed beyond recognizing their positions and that they form a horizontal line.
Step-by-step explanation:
The student has asked for help with some points: (1,8) and (5,8). To answer this question, we need to understand the relationship between the points. Both points have the same y-coordinate, which means they are located on a horizontal line at y = 8. Since the x-coordinates are different, we would draw a horizontal line from x = 1 to x = 5, all at y = 8. There is no need to simplify these points beyond recognizing their position on a graph.
If we were to plot these points along with other given examples, such as (0,2) to (3,2), or (0,3) to (3,3), those would also be horizontal lines located at their respective y-values. Each pair of points represents a horizontal line segment on a Cartesian plane.
