The correct interpretation of the slope and y-intercept for the equation \( y = 1.50x + 20 \) is:
The slope means that for every phone assembled (each increase of 1 in \( x \)), you receive an additional $1.50. The y-intercept means that you receive $20 a day regardless of the number of phones produced (when \( x = 0 \)).
So, 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.
