: How can we tell if a linear relationship is increasing or decreasing?AIMUnit 4 ACE#10,12; pp.19-20HW: Do Now:A woman has $40 in her bank account and deposits $20 each week. Is the relationship between weeks and money in the account linear? Explain. If it is, is the line increasing or decreasing? Ans: Yes, the relationship is linear because there is a constant rate of change, in this case, $20 per week. Since the money is being deposited, the amount of money is increasing, because when money is put into a bank, the account increased. We applied our knowledge of linear relationships to look at relationships with negative rates of change. We used the example of having $144 in a bank account and withdrawing $12 each week. Students sketched graphs, assigned variables, and wrote equations to model the situation.Classwork: Resources:https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=5&cad=rja&uact=8&ved=0ahUKEwjux-GX7NnKAhUKHT4KHd83DMYQtwIINzAE&url=http%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DQhjgmyp93OY&usg=AFQjCNGaUjZypJLDJTCz0FEBXy27GcMZdg&sig2=ikIvdOzwhl_rLUX04n_ggw&bvm=bv.113034660,d.cWw ## Leave a Reply. |
