Answer 1

Hi there !

I have attached the graph :-

Answer 2

Answer:

Refer the figure below.

Step-by-step explanation:

Given : Equations $x-y=8$ and $3x-3y=16$

To find : Plot the graph of the equations?

Solution :

We find the x-intercept and y-intercept of the equations so that we get two points and then we join them.

Equation 1 - $x-y=8$

x- intercept, Put y=0

$x-0=8$

$x=8$  

Point (8,0)

y- intercept, Put x=0

$0-y=8$

$y=-8$  

Point (0,-8)

Equation 2 - $3x-3y=16$

x- intercept, Put y=0

$3x-3(0)=16$

$3x=16$  

$x=\frac{16}{3}$  

Point $\frac{16}{3},0$  

y- intercept, Put x=0

$3(0)-3y=16$

$-3y=16$  

$y=-\frac{16}{3}$  

Point $0,-\frac{16}{3}$

Now, plot the graph of the equations.

Refer the attached figure below.
