Question

x + 3 = 0 is the equation of a line
(a) parallel to the x-axis and passing through (−3, 0)
(b) parallel to the y-axis and passing through (−3, 0)
(c) parallel to the y-axis and passing through (0, −3)
(d) None of these

Answer 1

(b) parallel to the y-axis and passing through (−3, 0)
Given equation: $x+3=0$
Or, $x=-3$
The equation of the line is parallel to the $y$-axis and passes through $(-3,0)$.
