It’s the slope formula i’m pretty sure . So it would be 5-5 and then 3-2 . so 0/-1
Answer:

Step-by-step explanation:
The time constant of the element X is:


The decay function has the following form:




8x4(-2x3)+8/2
I hope this is right!
y will decrease as well
direct variation is
y = kx where k is the constant of variation ( k > 1)
