Equation of the line parallel to the y- axis at a distance of 3 units from it and to its left is :
y = 3
y = -3
x = 3
x = -3
The correct option is D x = -3 The line is parallel to the y- axis and is at distance of 3 units from it. → the line meets the x- axis at either 3 or -3. It also given that the line is to the left side of the y- axis. So the line meets the x- axis at -3.
