Answer:
DF = 9.5
Step-by-step explanation:
Given 2 secants from an external point to the circle, then
The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is
DE × DF = DC × DB
5(5 + x) = 5(5 + 4.5) ← divide both sides by 5
5 + x = 5 + 4.5
5 + x = 9.5 ( subtract 5 from both sides )
x = 4.5
Then
DF = DE + EF = 5 + 4.5 = 9.5

It's just ascending order, easy.
Answer:
It means that for every 1 unit of time, the equation shows an increase of 8.38 units of distance.
Step-by-step explanation:
Slope is 
. Any number that does not have a denominator technically has a denominator of 1. Therefore, your slope is actually 
. That means you have a rise, or the vertical progression, of 8.38 while your run, or your horizontal progression, is 1. For every unit your line travels horizontally, it travels 8.38 units vertically. I hope this makes sense.
