If 1 inch = 8 miles
Then for every inch on the map there is 8 miles, so if there is 7.5 miles, just multiply inches by miles. which is 8 * 7.5 which equals 60 inches
1:8 = 5:40
1:5= 8:40
8 +5 = 13
13 + 7= 20

y = kx
substitute in and solve for k
14 = k(-4)

k = -7/2
y = -7/2 x
y = -7/2 * -6
y = 42/2 = 21
