(6)
5 units.
(a)
4 units
line parallel to the x-axis at a distance of

Aline which is parallel to y-axis is x=a

(i) Here, x=3

Hence, the equation of line parallel to y - axis is at a distance of 3 units to the right is x−3=0

(ii) Here, x=−2

Hence, the equation of the parallel to y- axis at a distance of 2 units to the left is x+2=0
