Question

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

Answer 1

For this case we have the following system of equations:

$y =-x-4\\y = x$

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

$x = -x-4\\2x = -4$

$x=\frac{-4} {2}\\x = -2$

So:

$y = -2$

Thus, the lines intersect at:$(x, y):(-2,-2)$

Answer:

See attached image

$(x, y): (- 2, -2)$

Answer 2

Answer:

(-2, -2)
