solve the system of equations by graphing and then classify them. x+y=16
x-y=-2

Question

anonymous · Answer

x=7 and y=9

anonymous · Answer

What are the options for classifying them? Do you know?

anonymous · Answer

It doesn't give any that is the entire problem?????

anonymous · Answer

They are both linear... Maybe that is the answer?

anonymous · Answer

I apologize it says classify the system. I don't know if that makes a difference?

anonymous · Answer

Oh okay. It looks like they intersect once

anonymous · Answer

rachel, do you understand how the solution was found?

anonymous · Answer

Systems of equations can either be parallel (they never intersect) they intersect once (two lines with different slopes) or they intersect an infinite number of times (they are actually the same line)

anonymous · Answer

That is, only if the two equations are linear.

anonymous · Answer

Typically they are then classified as:

Consistent & Dependent      (the same line with infinite solutions)
Consistent & Independent  (they have one intersection point)
Inconsistent   (they are parallel and never intersect)
