Answer:
Option b. degrees Fahrenheit/(mililiters)
Step-by-step explanation:
we know that
The formula to calculate the average rate of change between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
we have that
the units of the y-axis are [tex]{\°F}[/tex]
the units of the x-axis are [tex]{ml}[/tex]
therefore
the units of the the average rate of change are
[tex]m=\frac{\°F}{ml}[/tex]
