Answer:

See explanation below, and see attached photo for graphs

Step-by-step explanation:

To graph 3x + y = 6, find the x and y intercepts.  

We get the x intercept when y = 0, so plug in 0 for y and solve...

3x + 0 = 6

   3x = 6

    x = 2, so the x intercept is at (2, 0)

We get the y intercept when x = 0, so plug in 0 for x and solve...

3(0) + y = 6

   y = 6, so the y intercept is at (0, 6)

Plot those two points and draw a line through them

To graph -3x - 4y = 12, find the x and y intercepts.  

We get the x intercept when y = 0, so plug in 0 for y and solve...

-3x - 4(0) = 12

   -3x = 12

    x = -4, so the x intercept is at (-4, 0)

We get the y intercept when x = 0, so plug in 0 for x and solve...

-3(0) - 4y = 12

 

       -4y = 12

       

           y = -3, so the y intercept is at (0, -3)

Plot those two points and draw a line through them
