Answer:
B. A cow of 5 years is predicted to produce 5.5 more gallons per week.
Step-by-step explanation:
Let , where
is the age of the dairy cow, measured in years, and
is the predicted milk production, measured in gallons per week.
Besides, we consider and
, such that
, we define the difference between predicted milk productions (
) below:
(1)
If we know that and
, then the difference between predicted milk productions is:
That is, a cow of 5 years is predicted to produce 5.5 more gallons per week than a cow of 10 years. Hence, the right answer is B.
Answer:
y-intercept is 3
Step-by-step explanation:
We are given table
x: -8 -4 4 8
y: -3 0 6 9
We can select any two points
Firstly, we will find slope
now, we can plug values
now, we can use point slope form of line
we can plug values
now, we can solve for y
For finding y-intercept , we can plug x=0
So,
y-intercept is 3
