Decide which variable is for which axis. Slope-intercept form equation of a line is usually the first form students learn. If you choose a for the horizontal axis and b for the vertical axis, then solving both equations for b, you have the system:
-------------------
b=2a-2
----------------
b=(1/4)a-5
-------------------

The first equation has slope 2 and vertical intercept (0, -2);
the second equation has slope (1/4) and vertical intercept (0, -5).
Use those data to make the graph of each line.
