Which coordinate pairs lie on the x-axis? Select two answers.
A.(0,5)
B.(0,−13)
C.(4,0)
D. (−1,0)
B. (0,-13) and D. (-1,0) lie on the x-axis.
The coordinate pairs that lie on the x-axis have a y-coordinate of 0.
Therefore, the coordinate pairs that lie on the x-axis are:
C. (4,0)
D. (−1,0)
To determine which coordinate pairs lie on the x-axis, we need to identify the pairs where the y-coordinate is zero (y = 0).
Let's analyze the given coordinate pairs:
A. (0,5) - The y-coordinate is 5, which is not zero. Therefore, it does not lie on the x-axis.
B. (0,-13) - The y-coordinate is -13, which is not zero. Therefore, it does not lie on the x-axis.
C. (4,0) - The y-coordinate is 0, which is zero. Therefore, it lies on the x-axis.
D. (-1,0) - The y-coordinate is 0, which is zero. Therefore, it lies on the x-axis.
From the given options, coordinate pairs C and D have a y-coordinate of zero, indicating that they lie on the x-axis. Therefore, the correct answers are C and D.
