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