The answer would be choice 2 : Function 2 shows a greater rate of change, because Edwin spends $9 each month and Adam spends $7 each month.
I found this out because for Adam, you simply subtract the y-coordinates from each other and get 7 each time. Edwin clearly shows that he Spends $9 each month with the negative sign.
(The question is asking you to write your own problem, however, I will provide my own lame example)
My example:
There is a circus show in town this week. After looking at the total earnings of the show, it appears that it generated a total of $145,775 from ticket sales alone. The pricing was set at $25 a ticket, period. How many total tickets were purchased to the show?
Solving the problem:
The process is simple. Just as you asked in your question, divide the value of 145,775 (total number of dollars made off tickets) by 25 (total cost per ticket) to find the number of tickets bought.
145,775 divided by 25 is 5,831, the number of tickets sold.
Answer:
(0,5/2) y intercept
(15/7,0) x intercept
Step-by-step explanation:
To find the y intercept, let x = 0 and solve for y
0 - 6y = -15
Divide each side by -6
y = -15/-6
y = 5/2
(0,5/2)
To find the x intercept, let y = 0 and solve for x
-7x - 0 = -15
Divide each side by -7
-7x/-7 = -15/-7
x = 15/7
(15/7,0)
