3 is the lowest in that bound
Answer: ( -6 , -6.5 )
Step-by-step explanation:
The formula for calculating Mid - point is given by
M = (
,
)
= -5
= -7
= -9
= -4
substituting into the formula , we have
M =
, 
M =
, 
Therefore : mid point = ( -6 , -6.5 )
The equation that represents the amount earned is y = 12 + 2.5x
<h3>How to determine the equation?</h3>
The given parameters are:
- Chargers per day = $12
- Charges per walk = $2.5 per walk
Let the number of walks be x and the total charges per day be y.
So, we have:
y = 12 + 2.5x
Hence, the equation that represents the amount earned is y = 12 + 2.5x
