Question

Equation of a line parallel to x-axis and at a distance of 3 units upwards is :

• A. y = 3
• B. y = -3
• C. x = 3
• D. y = -3

Answer 1

The correct option is A y = 3

Equation of a line parallel to x-axis is of the form y = k.

Here is the distance is measured upwards of x-axis.

$\therefore$ equation of line is y = 3
