A gamer is observing her score, y, as she plays a video game. She currently has 4,200 points and is gaining 250 points for every minute, x, she plays.

Which of the following equations can be used to describe this linear relationship?

y = 250x − 4,200
y = 250x + 4,200
y = 4,200x − 250
y = 4,200x + 250
