Questions to Answer 1) How do the lines intersect? (How many times? ) 2) Examine the two equations. Are there clues that tell you how the lines will intersect? Explain. 3) Can a linear system have exactly two solutions? Three solutions? Explain.

A Linear System Can Have…

No Solution Parallel lines Will never intersect Slope is the same, y-intercept is different

One Solution Have one intersection Different slopes

Infinite Solutions Essentially the same line Intersect infinite times One equation is a multiple of the other

Success Criteria I CAN tell how two lines will interact by looking at the equation
