Answer:
y-2=2(x-1)
Step-by-step explanation:
Pick any two points from the line (example: (1,2) and (2,4))
Find the slope of them
Reminder: Slope is changes in y/changes in x or y2-y1/x2-x1
In this case, m= 4-2/2-1 which is 2
Now to use slope point form, chose any point and substitute it into this equation:
y-y1=m(x-x1)
Substituting it would get
y-2=2(x-1)
Or
y-4=2(x-2)
Exponential decay and range will be the set of natural numbers
