Solved Example on Horizontal Axis

Point B is 5 units to the left of point A on the horizontal axis. Find the coordinates of B if A is at (8, 7).

Choices:

A. (3, 7)

B. (13, 7)

C. (7, 8)

D. (8, 12)

Correct Answer: A

Solution:

Step 1: (8, 7)  8 on the x-axis and 7 on the y-axis.

Step 2: Point B is 5 units to the left of point A on the horizontal axis, i.e.,

x-axis.

Step 3: So, the x-coordinate of B is 8 – 5 = 3

Step 4: The coordinates of point B is (3, 7).
