Find the x-intercept and the y-interc
Then use them to graph the line.

Answers

x-intercept(s): (3,0)

y-intercept(s): (0,−9)

Answer:

The x is -3 and the y is -9 so the answer is (-3,-9)

Step-by-step explanation:

6x-2y=18

-6x -6x

-2y=-6x+18

-2y/-2=-6x/-2+18/-2

y= -3x -9

To graph you just mark it at -9 and go down 3 up 1; or you could go up 3 down 1
