Given the system of linear equations {y=-5
{y=3x-2

I am on the road so I apologize for the weird paper, but pictured is the graph. ;)

For the solution using the graph, identify where the two graphed lines intersect. In this case, the two lines cross at (-1,-5)

This can also be done algebraically.
Start by setting both given equations equal to each other, as both are equations of the same variable.
This leaves you with:
-5=3x -2

Next, begin to isolate your x-variable by adding the 2 on both sides.
After this , you end up with:
-3=3x

Solve for your x-value in your ordered pair solution by dividing by a positive 3 on both sides.

This gives you the final answer of a -1 for your x-value.

To find your y, take the x value you just found and plug it into e given equation with an x in it. This is y= 3x -2
Once you plug this in, you get:
3(-1) -2 = y

Multiply the 3 and the -1 together to simplify your equation.
This leaves you with:
-3 - 2
= y
Finally, subtract to find your value for y.
This results in a -5.

So your final ordered pair is (-1,-5)

I hope this helps :)
