Answer:
C
Step-by-step explanation:
The line of best fit is a linear function that is closest to all the points and shows the trend in the data. Since the data is going up ultimately, the slope of the line will be positive. Only B and C are options.
To find the best fit, draw a line through the center of the most points. This line will have as its y-intercept a value around 12 and a gentle slope. This means the answer choice is C.
4ft = 48 inches
12ft = 144 inches
48 inches + 5 inches = 53 inches
144 inches + 3 inches = 147 inches
147 inches - 53 inches = 94 inches
The answer is 94 inches
