The following data show the demand for a product (in hundreds) and its price (in dollars) charged in 9 different cities.
Price (x) .... | 25 | 15 | 18 | 20 | 19 | 23 | 21 | 17 | 22
Demand (y) | 23 | 55 | 47 | 45 | 40 | 30 | 42 | 59 | 32
The equation of the regression line for this data would be
a. y = -3.53x + 111.96
b. y = -3.53 + 111.96 x
c. y = -3.53x - 111.96
d. y = 111.96 + 3.53 x
e. y = 111.96x + 3.53
or is it none of these
