Answer:
Step-by-step explanation:
<u>Given function:</u>
It is a line with the slope of 1.
Average rate of change is same in any interval of the linear function and it equals to the rate of change or slope of the line.
You can calculate the average rate of change in the given intervals and you will always get the value of 1.
The first thing you should do is verify that the ordered pairs satisfy equality. If so, then that pair ordered belongs to the line. Let us begin:
3x-4y = 9
(-1.3)
3 (-1) -4 (3) = 9
-3-12 = 9
-15 = 9 (Does not belong)
(2/3, -7 / 4)
3 (2/3) -4 (-7/4) = 9
6 + 28 = 9
34 = 9 (Does not belong)
(-5, -6)
3 (-5) -4 (-6) = 9
-15 + 24 = 9
9 = 9 (Yes, it belongs)
(1, -3 / 2)
3 (1) -4 (-3/2) = 9
3 + 6 = 9
9 = 9 (Yes, it belongs)
answer
ordered pairs are
(-5, -6)
(1, -3 / 2)
The answer should be 1000$. I’m not positive but if it’s eight times the size, then you would multiply the price by 8.
