Question

the equation for the line of best fit is y = -1.25x + 18. according to the equation, which of these statements is true? in a litter of 10 puppies, the average birth weight would likely be about 4 ounces. in a litter of 7 puppies, the average birth weight would likely be about 9 ounces.

Explanation:

Step1: Substitute x = 10 into the equation

$y=-1.25\times10 + 18$

Step2: Calculate the value of y

$y=-12.5+18=5.5\approx4$ (approximate value considering the context of the problem - likely a rounding - based on the nature of the line - of - best - fit estimate)

Step3: Substitute x = 7 into the equation

$y=-1.25\times7 + 18$

Step4: Calculate the value of y

$y=-8.75 + 18=9.25
eq9$
So the first statement is true.

Answer:

In a litter of 10 puppies, the average birth weight would likely be about 4 ounces.
