In general the equation through (a,b) and (c,d) is
Can you see that this is a line and that both (a,b) and (c,d) are on it?
Here we're given (a,b)=(-6,-5) and (c,d)=(-4,-4)
Either of the last two are fine answers.

Answer:
The indifference point is 8 weeks.
Step-by-step explanation:
<u>First, we establish the total cost formula for each:</u>
x= number of weeks
Club:
Total cost= 20 + 15*x
Retail:
Total cost= 17.5*x
<u>Now, we equal both formulas and isolate x:</u>
20 + 15x = 17.5x
20 = 2.5x
8=x
The indifference point is 8 weeks.
<u>Prove:</u>
Total cost= 20 + 15*8= $140
Total cost= 17.5*8= $140
16 dollars each because you do 8x5 which equals 40 and do 168-40 which equals 128 / 8 equals 16
