The equation for the trend line above is y=29x−185
Using the equation, what is the expected sales if the temperature is 15 degrees
To find the expected sales when the temperature is 15 degrees, plug x = 15 into the equation y = 29x - 185:
y = 29(15) - 185
y = 435 - 185
y = 250
Therefore, the expected sales when the temperature is 15 degrees is 250.
