Answer : (i) Equation of line parallel to y – axis is given by x = constant, as the x – coordinate of every point on the line parallel to y – axis is 6 i.e. constant. Now the point lies to the right of y – axis means in the positive direction of x – axis,
So, required equation of line is x = 6.
(ii) Equation of line parallel to y – axis is given by x = constant, as the x – coordinate of every point on the line parallel to y – axis is – 3. Now point lies to the left of y – axis means in the negative direction of x – axis,
So, required equation of line is given as x = – 3.
