3. Diane records the following data after observing the high temperature at a beach and how many people visit that beach each day for a week.
High Temperature in degrees F (x): 78, 84, 82, 81, 87, 90, 80
Number of Visitors (y): 240, 312, 285, 291, 362, 389, 258
She uses the data to create a line of best fit using the points (84, 312) and (90, 389). What function represents Diane's line of best fit, and how many people can she predict would visit the beach on a day when the high temperature is 88°F?
A) Diane's line of best fit is represented by the function y=0.08x+305. and approximately 312 people would visit the beach on a day when the high temperature is 88°F.
B) Diane's line of best fit is represented by the function y=12.8x-766, and approximately 360 people would visit the beach on a day when the high temperature is 88°F.
C) Diane's line of best fit is represented by the function y= 13.1X-790, and approximately 363 people would visit the beach on a day when the high temperature is 88°F.
D) Diane sline of best fit is represented by the function y=12 8x-766, and approximately 67 people would visit the beach on a day when the high temperature is 88°F
