The Coordinate plane is formed by the intersection of two number lines, a horizontal number line and a vertical number line. The vertical number line is called the y-axis.
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: A
Step 1: The coordinate plane is formed by the intersection of two number lines, a horizontal number line and a vertical number line. The vertical number line is called the y-axis
Step 2: Graph 1 has the point P on the vertical number line i.e., on the y-axis.
A. (1, 0)
B. (-1, -1)
C. (0, 1)
D. (1, 1)
Correct Answer: C
Step 1: We know that, the ordinate of a point on the y-axis is equal to zero
Step 2: So, point (0,1) lies on y-axis.
