Answer:
(B) Time (min) 2 , 3 , 7 , 9
Temperature (°C) 60.6 , 64.3 , 79.1 , 86.5
Step-by-step explanation:
The rate of change is found by using the formula for slope:

For option A, this gives us
m =(64.4-61.0)/(3-2) = 3.4/1 = 3.4
This is not more than relationship A.
For option B, we have
(64.3-60.6)/(3-2) = 3.7/1 = 3.7
This is more than relationship A.
For option C, we have
(65.3-61.8)/(3-2) = 3.5/1 = 3.5
This is not more than relationship A.
For option D, we have
(64.6-61.0)/(3-2) = 3.6/1 = 3.6
This is not more than relationship A.
The points have the same x-coordinate, so they lie on a horizontal line. The distance between them is the difference between their y-coordinates.
2.5 - 1.4 = 1.1
The distance between the two points is 1.1

Step-by-step explanation:
(7-98)(7+98)
= 7^2 - 98^2
= 49 - 9604
= -9555
