Aftab tells his daughter,"Seven years ago,$I$ was seven times as old as you were then. Also,three years from now,$I$ shall be three times as old as you will be." Represent this situation algebraically and graphically.

Which of the following pairs of linear equations are consistent/inconsistent? If consistent,obtain the solution graphically: $2x - 2y - 2 = 0, 4x - 4y - 5 = 0$.

The solution set of a pair of equations $5x - 5y = -5$ and $\frac{3x}{2} - \frac{3y}{2} + \frac{3}{2} = 0$ is.........

Solve the following pair of linear equations in two variables using a graph: $x + y = 8$ and $x - y = 2$.

Draw the graphs of the lines $x=-2$ and $y=3$. Write the vertices of the figure formed by these lines,the $x$-axis and the $y$-axis. Also,find the area of the figure.
