Question

Help me answer this!!!

Answer 1

Answer/Step-by-step explanation:

Year = x

Weight (kg) = y

Rate of change between 2010 and 2011 =
`(y_2 - y_1)/(x_2 - x_1)`

Where,

`(2010, 35) = (x_1, y_1)`

`(2011, 30) = (x_2, y_2)`

Plug in the values

`= (30 - 35)/(2011 - 2010)`

`= (-5)/(1) = -5`

Rate of change = -5kg per year

This means that there was a decrease in the weight of the winning dog form 2010 to 2011 by 5 kilograms
