Question 987225: My kids’ bathtub is being drained. Since it is an ordinary tub, it can be modeled by the function
V(t) = -15t + 45 where V(t) is the volume of the tub in gallons and t is the time that has passed in minutes.
1.Identify the slope of the function V(t) = -15t + 45. Clearly interpret this slope in the context
of the problem. Use complete sentences in your answer.
2.Identify the vertical intercept of the function V(t) = -15t + 45. Clearly interpret the vertical
intercept in the context of the problem. Use complete sentences in your answer.
3.Identify the horizontal intercept of the function V(t) = -15t + 45. Clearly interpret the
horizontal intercept in the context of the problem. Use complete sentences in your answer.
For a linear equation of the form , the slope is the coefficient on the variable.
The -coordinate of the -intercept is the constant term in . The -intercept is the point . This represents the value of the function when the input value is zero.
The -coordinate of the -intercept is the value of that is required to make the value of the function be zero. In the case of , this value is , and the -intercept is then the point .
