Answer:
see below!
Explanation:
you would graph each linear equation in a system as you would seperately.
the only difference is that they go on one graph.
so if you were to graph one linear equation, say it looked like
y=mx+b
all you have to remember is that b is the y intercept, or the value of y when x is 0
m is the slope. slope often looks like a fraction which is rise/run
hope that helps :)
