Solve the system of linear equations by graphing y=-x-4 y=x were do the lines intercept

(-2, -2)

Step-by-step explanation:

For this case we have the following system of equations:

If we substitute the second equation in the first we have:

So:

Thus, the lines intersect at:

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
