Graphing Systems of Linear Equations. Use graph paper if you have it, or you can sketch the graphs 1. y = - 2x + 5

y = 3x + 0

2. x + y = -2

-3x + y = 6

Marcus and cody both leave the park at the same time, but in opposite directions. if cody travels 6 mph faster than marcus and after 4 hours they are 64 miles apart, how fast is each traveling? solve using rare times time = distance.
