The formula for distance is (y2-y1)/(x2-x1)
Answer:
20 times.
Step-by-step explanation:
To find out how many times larger a number is than another number, simply divide the two numbers, with the larger number being in the numerator.
For example, how many times larger is 6 than 2? The answer would be 6/2 or 3 times larger.
So, divide 8*(10^3) and 4*(10^2):

Expand the expressions. This is the same as saying:

We can cancel two of the 10s since they are in both the numerator and the denominator. Thus, only one 10 is left in the numerator:

Simplify:

Therefore, 8*(10^3) (or 8000) is 20 times larger than 4*(10^2) (or 400).
