Question

determine graphicallythe x value when y= -3 in the given equation -x + 3y=-6

Answer 1

First off, Isolate your x and plug-in the y-value.

Answer 2

-x +3(-3)= -6

Answer 3

Isolate your x now.

Answer 4

So -x = 9-6

Answer 5

what does that mean ?

Answer 6

Make x by itself.

Answer 7

Now, x = -3

Answer 8

Do you understand so far?

Answer 9

so y and x are the same value?

Answer 10

Yes so you have coordinates of (-3,-3)

Answer 11

Now you have two points that you can draw to make a line graphically.

Answer 12

ok, thanks

Answer 13

You have the -6 that goes on the y-axis and the (-3,-3)

Answer 14

Your line should look a little like this. It's not up to scale and it's poorly drawn but it still gives you an idea.
