Use the following information to solve questions 2 and 3. A farmer has 2 data points regarding the price and quantity demanded of tomatoes that he wants to use to calculate a linear relationship between the 2 variables. He observes that when the price of tomatoes is $2/lb the quantity demanded is 15lb. On the other hand, when the price of tomatoes decreases to $1/lb, the quantity demanded becomes 201b. Based on these 2 points, the farmer wants to calculate the equation of a straight line of the form price = a + b Quantity, where a and b are the y-intercept and slope, respectively. Question 3 10 pts Based on the 2 data points available, what is the y-intercept of the straight line (i.e., what is the value of a)? 4 O 5 1 o 2
