This is a proportional relationship. So any example that shows as x increases, y decreases.
A real life example would be where
x=time i let the pool drain
y=amount of water left over
As I let the time I let the pool drain increase, the amount of water left in the pool decreases.
Answer:
y=2.50+175*(x-1)
$4727.50
Step-by-step explanation:
y=2.50+175*(x-1)
The first km costs 2.50 which is why you add it. You do x-1 because the 175 is charged for each additional km. So, if you traveled one km it would cost 2.50.
y=2.5+175*(28-1)
y=2.5+175*27
y=2.5+4725
y=$4727.50
Step by step explanation :
The two points are ,
We can find the midpoint by finding the median of x coordinate and y coordinate .
