Answer 1

this is the answer for your question

Answer 2

Refer the attached graph.

Step-by-step explanation:

To find : Draw the graph of the linear equation $3x-7y=21$ ?

Solution :

We plot the linear equation by two intercept points.

The x-intercept is when y=0,

Put y=0 in the equation,

$3x-7(0)=21$

$3x=21$

$x=\frac{21}{3}$

$x=7$

The point is (7,0).

The y-intercept is when x=0,

Put x=0 in the equation,

$3(0)-7y=21$

$-7y=21$

$y=-\frac{21}{7}$

$y=-3$

The point is (0,-3).

We plot the points and draw a straight line.
