e) y = –8
2. Find the equation of the line passing through (4, – 4) and parallel to the y-axis.
c) x = 4 –4 e) y = –4
3. A municipal corporation of a city undertakes a project to build a new road at (–4, 1). There is another road which is expressed using y = 2x – 3. Find the location of the road (in terms of the equation of a line) such that the two roads never meet each other.
a)y=2x–9 y = – 2x + 9
c) 2y = – x – 6 2y = – x – 10
e) y = 2x + 9
