Substitution and Elimination Test

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)
