The graph models the amount of radioactive element present over the cours of a 2 minute experiment. What is the avearge rate of change of the amount of the element over the 2 minute experiment?

a -12.5 g/min
b 2 g/min
c. 2.5 g/min
d. -3.75 g/min

24/56=hx^7

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

correct answer is b. 27/8
