x + 5 = 0
⇒ x = - 5
This equation represents a vertical line that is parallel to the y-axis, where the x-coordinate is always −5.
Hence, option 2 is the correct option.

For line y = 20 + 2x, if x = 20, the value of y is :
40
60
80
0
A point that lies on the line 2x - 3y = 4 can be taken as :
(-5, -2)
(-5, 2)
(5, 2)
(5, -2)
The lines y - 2 = 0 and 2x + 3y = 12 cut each other at point :
(-3, 2)
(3, -2)
(-3, -2)
(3, 2)
