If BOTH equations are in slope-intercept form then the--------------? method would be best, but the------------? method would also be effective since both y's are already by itself.

If ONE of the equations is solved for x or y and the other equation is not, then the----------? method is best.

If BOTH equations are lined up in standard form & the coefficients of x or y are opposites then the BEST method is definitely the-----------? method.

If BOTH equations are lined up in standard form the elimination method would be best. But if the coefficient of x or y is 1, then the-------------? method is also effective.

PLZ HELP MEEE WITH THIS

If BOTH equations are in slope-intercept form then the-graphing-? method would be best, but the-substitution-? method would also be effective since both y's are already by itself.

If ONE of the equations is solved for x or y and the other equation is not, then the-substitution-? method is best.

If BOTH equations are lined up in standard form & the coefficients of x or y are opposites then the BEST method is definitely the-elimination--? method.
