Can someone help me with this? I don't understand it. :( http://prntscr.com/6sapl9
You are given a linear equation, they want you to find another linear equation such that the system of two linear equations have no solution, a unique solution, or infinite solutions. In each case you will need a different linear equation.
@24/7 Do you know this? A system will have no solutions when the two lines have the same slope but different y-intercepts A system will have infinitely many solutions when it is the same exact line with the same slope and same y-intercept. A system will have one exact solution when the two lines intersect at one point.
Here are some examples: http://www.mathwarehouse.com/algebra/linear_equation/systems-of-equation/index.php
change the function to y=mx+b. It will be easier that way.
