[tex]-\frac{1}{3}x[/tex] + y = -1 ⇒ y = [tex]\frac{1}{3}x[/tex] - 1
To graph this line, plot a point at the y-intercept (0, -1), than plot the next point using the rise over run from the slope [tex](\frac{1}{3})[/tex] by counting up 1 and to the right 3 of the y-intercept. This gives you a second point of (3. 0). Draw a line through those two coordinates.
Answer: Plot (0, -1) and (3, 0) and draw a line through them.

y = 4 + [tex]\frac{1}{3}x[/tex] ⇒ y = [tex]\frac{1}{3}x[/tex] + 4
Same as above. Plot the y-intercept (0, 4) and then use rise over run from the slope to plot (3, 5).
Answer: Plot (0, 4) and (3, 5) and draw a line through them.

You should end up with two PARALLEL lines. Since the lines never intersect, there are no solutions to this system of equations.
Answer: No Solution
