Step-by-step explanation:
The slope-intercept form of a line is:

Where m is the slope and b is the intersection of the line with the y-axis.
Given the first equation 
You can identify that:
b=-1
Substitute y=0 to find the intersection with the x-axis

This line passes through the points (0,-1) and (-2,0)
Given the second equation:

Solve for y:

It passes through the point (0,-4).
Now, you can graph. See the figure attached.
It has one solution,which is the point of intersection of both lines: (6,-4)
