Graphical method of finding solution of a pair of LE

Q. The pair of equations $x=a$ and $y=b$ graphically represents lines which are

1. intersecting at (a, b)
2. parallel
3. coincident
4. intersecting at (b, a)

Q. What is the solution for the two lines given in the graph?

1. $x=0,y=0$
2. $x=4,y=2$
3. $x=5,y=2$
4. $x=-5,y=2$

Q.

On the basis of the graph shown below which shows the graphical representation of a pair of linear equations, the pair of linear equations has _______________solution(s).

1. four

2. zero

3. a unique

4. infinite

Q. What can one observe about a solution to the given lines?

1. A solution is not possible as the lines do not intersect.
2. The lines will coincide and will have infinite solutions.
3. When the lines are extended further they will intersect and point of intersection will be the solution.
4. The lines are parallel and hence no solution is possible.

Q. What is the solution for the two lines given in the graph?

1. x = -3, y = 9
2. x = -3, y = -9
3. x = 9, y = -3
4. x = -9, y = -3
