The graph of the linear equation $5x - 3y = 20$ intersects the $x$-axis at:

If the point $(5, 2)$ lies on the graph of the equation $3x + 2y = k$,then $k = \ldots$

If $(2,0)$ is a solution of the linear equation $2x + 3y = k,$ then the value of $k$ is

Draw the graph of each of the equations given below. Also,find the coordinates of the points where the graph intersects the coordinate axes:
$1. 3x + 5y = 15$
$2. 5x - 2y = 10$
$3. 4x + 3y = -12$
$4. 3x - 7y = 21$
$5. x - y = 0$
$6. 2x - 3y = 0$
$7. x - y = -5$
$8. 5x - 3y = 15$

Write the following equation in the form of a linear equation in two variables: $4x - 17 = 0$.

If the point $(3,4)$ lies on the graph of $3y = ax + 7$,then find the value of $a$.
