Solution

(i) The equation of given line is x = 4. This equation does not contain the term of y. So, the graph of this line is
parallel to y-axis passing through the point (4, 0).

(ii) The equation of given line is x + 4 = 0 or x = –4. This equation does not contain the term of y. So, the graph
of this line is parallel to y-axis passing through the point (–4, 0)

(iii) The equation of given line is y = 3. This equation does not contain the term of x. So the graph is a parallel line to x-axis and passes through (0,3)

(iv) y = -3

(v) x = - 2

(vi) x = 5

(vii) y + 5 = 0

(viii) y = 4
