If P (5, 1), Q (8, 0), R (0, 4), S (0, 5) and O (0, 0) are plotted on the graph paper, then the point(s) on the x-axis are
a. P and R
b. R and S
c. Only Q
d. Q and O

Solution:

The points given are P (5, 1), Q (8, 0), R (0, 4), S (0, 5) and O (0, 0)

Let us plot these points as x and y coordinates on a graph paper 

From the graph, we observe that the points (8, 0) and (0, 0) are on the X axis

Therefore, the points on the x-axis are Q and O.
