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?

Answer 1

Answer:

y = 2

Step-by-step explanation:

A line parallel to the x-axis will be horizontal and cross through the y-coordinate 2. It is also written as y = b where b is the y-intercept.

So the line through (1,2) must be y = 2.
