Graph the following:

1.x - y = -5

y = -4 - 2x

2. y = x - 2

x - 2y = 4

Solve each system of equations using the SUBSTITUTION or ELIMINATION method.Show the steps.

3.x - 4y = -18

3/4 + (1/4)y = x

4.Describe the results for two parallel lines.Give an example of a system that would yield this system.
