Question

Equation of a line parallel to y-axis and at a distance of 7 units from it to its left side is:

• A. y = 7
• B. y = -7
• C. x = 7
• D. x = -7

Answer 1

The correct option is D x = -7

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

Here is the distance is measured to left side of y-axis.

$\therefore$ equation of line is x = -7
