Answer:
Step-by-step explanation:
(2, 4)
(2, - 5)
"rise" = - 5 - 4 = - 9
"run" = 0 ⇒ slope (rate of change) is undefined
Understanding Rate of Change (ROC)
The calculation for ROC is simple in that it takes the current value of a stock or index and divides it by the value from an earlier period. Subtract one and multiply the resulting number by 100 to give it a percentage representation.
5/8 of a quart.
That would be 28/32 - 1/4
= 28/32 - 8 /32
= 20/32
= 5/8 of a quart.
