Graphing
When both equations are in slope intercept form
Elimination
When equations are in standard form or when you have opposite coefficients
Substitution
When one equation is already solved for x and y
one solution
different slopes
no solution
same slope different y-intercepts
infinitely many solutions
same slope same y-intercept
how to make it slope intercept form
take away the x from both sides then divide by the y (opposite if needed)
