Number of months that Lance lived in Portugal: x
Number of months that Lance lived in Brazil: y

Lance lived in Portugal and Brazil for a total of 14 months to learn Portuguese:
(1) x+y=14

He learned an average of 130 words per month when he lived in Portugal:
Number of words that Lance learned in Portugal: 130x

and an average of 150 new words per month when he lived in Brazil:
Number of words that Lance learned in Brazil: 150y

In total, he learned 1920 new words:
(2) 130x+150y=1920

Write a system of equations to represent this situation:
(1) x+y=14
(2) 130x+150y=1920

The correct graph is the second one, with the points being at (-6,0), (2,0) and reaching down to (-2,-8)
