An island has an area of 728 square miles. about 83,000 people live on the island. which expression can be used to calculate the constant of proportionality that represents the number of people per square mile?

Area of island = 728 square miles

Number of people living on the island = 83,000

Let us say "x" represents the number of people living on the island per square mile.

We are given number of people living in 728 square mile of island =83,000

So we will apply unitary method here to find people living per square mile of island.

x= number of people living in 728 square mile divided by area of island.

x=83000/728 =114

So number of people living per square mile of island is x=114

it's

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
