Answer:
my best advice: look at the y-intercepts!
Step-by-step explanation:
when the equations are set out like this, the last number (in this case "+4" and "-2"), represents where they cross the y axis. this gives you a great place to start.
if you plot (0, 4) for the first equation, you can then move right one square and down one square to get the next point in the equation.
the next one starts with (0, -2) and goes right one square and up two
