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