Answer:
the given system is
The first line is already graphed.
We want to graph
We can do this by plotting two points and drawing a straight line through them.
When we choose x=0, we substitute into the equation and solve for y.
So we plot (0,-4)
Also, when y=0, we substitute and solve for x.
So we plot the point (-4,0)
We now use a straight edge to draw a straight line through these two points to obtain the graph shown in the attachment.Explanation:
