Answer:
y = - 0.833 + 29.5
y = 17
Step-by-step explanation:
Drawing a best fit line through the data points:
The approximate regression model would have an intercept of about 29.5
The slope = Rise / Run = (y2 - y1) / (x2 - x1)
The slope = (5 - 25) / (27 - 3) = 20 / 24 = -0.8333
The regression equation is thus :
y = mx + c
m = slope ; c = intercept
y = - 0.833 + 29.5
B)
x = 15
y = - 0.833(15) + 29.5
y = -12.5 + 29.5
y = 17
