B. Solve systems of two linear equations in two variables algebraically, and estimate solutions by graphing the equations. Solve simple cases by inspection. For example, 3x + 2y = 5 and 3x + 2y = 6 have no solution because 3x + 2y cannot simultaneously be 5 and 6.

Identify how many solutions by inspection.This will help you with the IXL on finding the number of solutions to a system of equations.
It is all about the SLOPE! Look at the slopes first and that will give you an idea about how the lines are interacting with each other. |
