Warning The material up to this point, most of you had probably seen at some point The material in chapter 5-6 MAY be new Even if not new, the way it is presented is probably new You MUST keep up with the work or you will get lost in future lectures.
Linear Function Recall for linear functions Our basic formula was A: by + mx = 0 B: y = b + mx C: y = bx + m D: x = b + m*y b- A: our beginning (initial value) B: slope C: x-intercept D: used in (m,b) a point on the line m-slope or rate of change (which is CONSTANT) Could read from the table Might be given verbally

Church Growth Start with 10 people Pastor gets 2 people per month to join Find equation to describe. A: P = 2 + 10m B: P=10+2m C: 10P + 2m =0 D: m = 10 + 2p An “additive” Obj100

Church Growth Another way to model the growth Start with 10 people Each month- everyone gets someone else to join Can still fill out a table Obj101 When m =1, P = A: 12 B: 20 C: 30 D: 40 When m = 2, P = A: 30 B: 22 C: can’t tell D: 40 When m = 3, P = A: 50 B: 60 C: 80 D: 70
