State whether the following statement is True or False and justify your answer:
Every point on the graph of a linear equation in two variables does not represent a solution of the linear equation.

The force exerted to pull a cart is directly proportional to the acceleration produced in the body. Express the statement as a linear equation of two variables and draw the graph of the same by taking the constant mass equal to $6 \,kg$. Read from the graph,the force required when the acceleration produced is $(i)$ $5 \,m/s^2$,$(ii)$ $6 \,m/s^2$.

If $(k, 3)$ is a solution of the equation $2x + 5y = 17$,find the value of $k$.

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

Which of the following is not a solution of the equation $2x + 7y = 28$?

One of the solutions of the linear equation $3x + 5y = 30$ is $\ldots \ldots . .$
