y = kx, where k is the constant of proportionality.
To find k, we simply substitute in the given x and y values, and solve for k. i.e we to get:
8 = k x 2.
k = 8/2 = 4.
so y = 4x

#5.
First you divide 200 miles by 5, then multiply that number by 7.
Why?
You have to find out how many miles one inch represents to know how many miles 7 inches is.

Divide 48 by 6, then multiply that number by 3.
Why?
For every 6 yards of material, 3 yards of trim is used to make one costume. So when you divide 48 by 6, you find out how many yards of material us needed to make ___ costumes. Multiplying ___ by 3 will show how many yards of trim she needs.
