The correct interpretation of the slope and y-intercept from the equation \( y = 1.50x + 20 \) is as follows:
-
Slope (1.50): This means that for every phone assembled (each unit increase in \( x \)), your total pay increases by $1.50. Therefore, you receive $1.50 for each additional phone you assemble.
-
Y-intercept (20): This means that you receive $20 a day regardless of the number of phones produced. This is your base pay when you assemble zero phones (when \( x = 0 \)).
Based on these interpretations, 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.
