Question

based on the line of best fit, which value is most likely the attendance at the water park on a day when the high temperature is 95°f? 500 380 440 320

Explanation:

Step1: Find two points on the line

From the graph, the line passes through (70, 100) and (90, 320).

Step2: Calculate the slope

Slope $m = \frac{320 - 100}{90 - 70} = \frac{220}{20} = 11$.

Step3: Find the equation of the line

Using point-slope form with (70,100): $y - 100 = 11(x - 70)$. Simplify: $y = 11x - 770 + 100 = 11x - 670$.

Step4: Predict attendance at 95°F

Substitute $x = 95$: $y = 11(95) - 670 = 1045 - 670 = 375$.

Answer:

B. 380
