Question

Which of the following is the equation of a line that passes through the point (1,2) and is parallel to the x-axis?

A. x=2
B. y=2
C. y=1
D. x=1

Answer 1

The equation of line would be y = 2

Explanation:

Since the x-axis is horizontal, we would look for another horizontal line to be parallel. All horizontal lines can be written as y = (a number). We can find that number as the y-coordinate in the ordered pair (2)

y = 2
