Answer:
the range represents the number of users each month for 24 months
Step-by-step explanation:
this is because the graph shows a 24 month period.
We need to solve the speed formula for d. To do so, let's start by moving the number of the left hand side:

Square both sides to get rid of the square root:

Now plug the known value of the speed to find the distance:

So the closest answer is the last one: d=0.155km
Horizontal- y=-1/2
vertical- x=5
x intercepts- (-2,0)
y intercepts- none
hole- (0, 1/5)
