Answer:

Step-by-step explanation:
we know that
The equation of the line in slope intercept form is equal to

where
m is the slope
b is the y-intercept
so
1) Find the slope of the given line 
The slope is 
2) Find the y-intercept of the given line 
The y-intercept is 
therefore
The equation of the line with


is equal to

Answer:
See below
Step-by-step explanation:
The first one IS decay...as 'x' increases the function decreases
the second and third are NOT ...as 'x' increases the value increases
radioactive decay IS decay (obviously)
the one with e^2x is not ....it grows exponentially as x grows
and finally the last one is decay because as x gets larger the value of y gets smaller
I think it’s Integer I’m not sure
