Choose the best method for solving this system of equations:
Y = 2X +7
Y = 5X +

• I should solve this system of equations using graphing because both equations are in slope-intercept format (Y=MX+B).
• I should solve this system of equations using substitution because one of the equations tells me “X=____”, or “Y =____”
• I should use elimination because both equations are in standard form (example: 2X + 3Y = 10)
