a.
To evaluate y- intercept
a.
Answer to Problem 4.1.3P
The y- intercept is 1.
Explanation of Solution
Given information: Equation for puppy’s weight,
Where, m is age in months
p is weight in pounds
Formula Used:Equation for line,
Where, m is slope
c is y-intercept
Calculation:
Comparing the given equation with the equation of line,
Hence, y- intercept is 1
y- intercept indicates the initial weight of the puppy
Conclusion:The y- intercept is 1.
b.
b.
Answer to Problem 4.1.3P
The slope is 7.5
Explanation of Solution
Given information: Equation for puppy’s weight,
Where, m is age in months
p is weight in pounds
Formula Used: Equation for line,
Where, m is slope
c is y-intercept
Calculation: Comparing the given equation with the equation of line,
Hence, slope is 7.5
Slope indicates the rate of change of weight of the puppy
Conclusion: The slope is 7.5
