Write the following as an equation in two variables:
$4y = 24$

If the point $(a, a-2)$ lies on the graph of the equation $3x + 5y = 30$,find the value of $a$.

Solve the equation $3x - 1 = x + 7$ and represent the solution$(s)$ on $(1)$ the number line $(2)$ the Cartesian plane.

The autorickshaw fare in a city is as follows: For the first kilometre,the fare is ₹ $10$,and for the subsequent distance,it is ₹ $3$ per $km$. Taking the distance covered as $x$ $km$ and the total fare as ₹ $y$,write a linear equation for this information and draw its graph. Find the total fare for a journey of $4$ kilometres from the graph.

In a Cartesian plane,the graph of the equation $y=5$ is parallel to the ........ axis.

The graph of the linear equation $2x + 3y = 6$ is a line which meets the $x$-axis at the point
