The coordinate plane is formed by the intersection of two number lines, a horizontal number line and a vertical number line. The horizontal number line is called the x-axis.
The equation of x-axis is y = 0
The y-coordinate or ordinate of every point on x-axis is equal to 0
The figure shows the coordinate plane formed by the intersection of the x- and y- axes.
Their point of intersection is called the origin.
A. Graph 1
B. Graph 2
Correct Answer: B
Step 1: The coordinate plane is formed by the intersection of two number lines, a horizontal number line and a vertical number line. The horizontal number line is called the x-axis
Step 2: Graph 2 has the point P on the horizontal line i.e., on the x-axis.
A. (1, 1)
B. (1, 0)
C. (0, 1)
D. (-1, -1)
Correct Answer: B
Step 1: We know that, y-coordinate or ordinate of every point on x-axis is equal to 0
Step 2: Therefore, among the ordered pairs given (1, 0) lies on x-axis
