Which pair of points have equal x-coordinates?
Understand the Problem
The question is asking to identify which pair of points among the given options has the same x-coordinates based on their positions on the coordinate plane.
Answer
The answer is points Q and R.
Answer for screen readers
The pair of points that have equal x-coordinates is points Q and R.
Steps to Solve
- Identify the coordinates of each point
From the graph, we can observe the coordinates of the points as follows:
- Point Q: $(x_1, y_1)$ at the position (2, 5)
- Point R: $(x_2, y_2)$ at the position (2, -5)
- Point S: $(x_3, y_3)$ at the position (-3, -5)
- Point T: $(x_4, y_4)$ at the position (7, 2)
- Compare the x-coordinates of the points
Now, we'll compare the x-coordinates of the identified points:
- For points Q and R: both have $x = 2$.
- For point S: $x = -3$.
- For point T: $x = 7$.
- Determine which points have equal x-coordinates
Since points Q and R have the same x-coordinate ($2$), they are the answer.
The pair of points that have equal x-coordinates is points Q and R.
More Information
Points with the same x-coordinate lie vertically aligned on the coordinate plane. This indicates that they are either above or below each other along the y-axis.
Tips
- Confusing x-coordinates with y-coordinates. Always check whether you are comparing x or y values.
- Not adequately plotting the points or misreading their positions on the graph.
