Question
You work for a manufacturing company on a production line that manufactures cell phones. You are paid $20 a day plus $1.50 for each phone that you assemble. Interpret the slope and y
-intercept of the equation of the trend line y=1.50x+20
.(1 point)
Responses

The slope means that, for every 20 phones assembled, you receive $1.50. The y
-intercept means that you receive $20 a day regardless of the number of phones produced.
The slope means that, for every 20 phones assembled, you receive $1.50. The y -intercept means that you receive $20 a day regardless of the number of phones produced.

The slope means that, for every 1.50 phones assembled, you receive $1. The y
-intercept means that you receive $20 a day regardless of the number of phones produced.

To interpret the equation of the trend line \( y = 1.50x + 20 \):

  • Slope (1.50): This represents the amount earned for each phone assembled. Specifically, for each phone (each unit increase in \( x \)), you earn an additional $1.50.

  • Y-intercept (20): This is the starting pay you receive regardless of the number of phones produced. It means you receive $20 a day even if you assemble zero phones.

Based on this interpretation, the correct response is:

The slope means that, for every phone assembled, you receive $1.50. The y-intercept means that you receive $20 a day regardless of the number of phones produced.
