Line and Intersections

When does a system of equations not have a solution (AKA intersection point)?

• When it two different versions of the same line

• When they have different slopes

• When they have the same y intercept

• When the lines are parallel

Add these equations together and report the resulting equation: x+y=10, 3x-5y=23
