Can any one help with this?

Question

Describe the graph. Indicate whether the line would be a solid or a dotted line. Indicate which quadrant would be shaded
x + y = 4
–x + y = 2

Answer 1

There is only shading with inqualities.

The two individual equations shown each define solid lines -- with no shading. The system (both equations) has only one solution, which is a point (1, 3).

Answer 2

First of all there would be no shading because these are equations, not inequalities. And therefore they would be solid.

The graph would be two intersecting lines. That's it.
