Question

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

Answer 1

y=250x+4,200 is the answer

Answer 2

Answer: y=250x+4200
the reason behind y=250x+4200
A linear relationship is using the slope form:y=mx+b.M is equal to 250 points because she is earning for each x min. B is equal to 4,200 points because it was points to started with. So it made as an additional point to our equation. Which led to our answer: 250x+4,200=y
