• they have the same slopes. 
• they have the same y-intercept.
• they have different slopes.
• they have different y-intercepts.

y = x² + 7x - 2
y = 2x - 6

• x = 4, y = 2; x = 3, y = 5
• x = -4, y = 2; x = -1, y = -8
• x = -2, y = -10; x = 3, y = 0
• x = 1, y = -4; x = 0; y = -6

Christian had brochures printed for a new business venture. Christian originally ordered 4 boxes of black-and-white brochures and 3 boxes of colour brochures, which cost a total of $134. After those ran out, Christian spent $120 on 3 boxes of black-and-white brochures and 3 boxes of colour brochures. Which system represents this situation?

• x+y=134
  x+y=120
• 3x+3y=134
  4x+3y=120
• 4x+3y=134
  3x+3y=120
• 7xy=134
  6xy=120
