Chapter 7 Interpreting Linear Equations And Models

Question 1

When given a model and where it asks you the best interpreatation for this number, what does all the numbers mean? V(t)=240000-5000t

Answer 1

This is in y=mx+b form, the y-intercept b will typically designate an initial value, the value when x=0

Question 2

what is the slope by definition?

Answer 2

Is a rate of change, the increase or decrease in y for each unit increase in x.

Question 3

When dealing with linear models that represent possible combinations, what is the key?

Answer 3

To look at either the x-intercept or y-intercept.
