Just to help you, that formula is saying that 1 mile is equivalent to 5280 feet, i.e. the number of feet is equal to 5280 * number of miles.
So, you know the number of feet = 21,120 and have to convert that into the equivalent number of miles:
f = 5280m => m = f / 5280
m = 21,120 / 5280 = 4 miles
Answer: 4 miles

x- intercept (- 8, 0), y- intercept (0, 8)
Step-by-step explanation:
To find the y- intercept, let x = 0 in the
equation and solve for y
y = 0 +8 =8 (0,8 ) y -intercept
To find the x- intercept, let y = 0 in the
equation and solve for x
x + 8 = 0 ( subtract 8 from both sides )
x=- 8 (-8, 0) intercept.
