Answer: The graph is attached.
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.
Given the first equation:

You can identify that:

By definition, the line intersects the x-axis when
. Then, subsituting this value into the equation and solving for "x", you get that the x-intercept is:

Now you can graph it.
Solve for "y" from the second equation:

You can identify that:
Notice that the slopes and the y-intercepts of the first line and the second line are equal; this means that they are exactly the same line and the System of equations has<u> Infinitely many solutions.</u>
See the graph attached.
