Question

20 POINTS

Answer 1

Answer:

B. y=−0.18x + 10.06

Step-by-step explanation:

Let us compute the average of the slope between points

(9.9-10)/(1-0) = -0.1

(9.6-9.9)/(2-1) =  -0.3

(9.5-9.6)(3-2) = -0.1

(9.4-9.5)/(4-3) = -0.1

(9.2-9.4)/(5-4) = -0.2

(9 - 9.2)/(6-5) = -0.2

(8.7-9)/(7-6) = -0.3

average is (0.1+0.3+0.1+0.1+0.2+0.2+0.3)/7 = -0.186

The y- intercept we know from point (0,10) is ten

Thus, from the choices given, the equation that best first the data is

y=−0.18x + 10.06.
