**Question:**

Draw the graph of each of the following equations.

(i) *x *= 4

(ii) *x *+ 4 = 0

(iii)* y* = 3

(iv) *y* = –3

(v) *x *= –2

(vi) *x *= 5

(vii) *y *+ 5 = 0

(viii) *y* = 4

**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 of this line is parallel to *x*-axis passing through the point (0, 3).

(iv) The equation of given line is *y* = –3. This equation does not contain the term of *x*. So, the graph of this line is parallel to *x*-axis passing through the point (0, –3).

(v) The equation of given line is *x* = –2. This equation does not contain the term of *y*. So, the graph of this line is parallel to *y*-axis passing through the point (–2, 0).

(vi) The equation of given line is *x* = 5. This equation does not contain the term of *y*. So, the graph of this line is parallel to *y*-axis passing through the point (5, 0).

(vii) The equation of given line is *y* + 5 = 0 or *y* = –5. This equation does not contain the term of *x*. So, the graph of this line is parallel to *x*-axis passing through the point (0, –5).

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