Use the distance formula to find the distance between (1,3) and (4,-1)

That distance is 5 units.

Step-by-step explanation:

There are several very similar forms for the distance formula.

One is d = √[ (x2 - x1)^2 + (y2 - y1)^2 ].

x1 and x2 are the two given x values, which in this case are 1 and 4.

Then we have:  d = √[ (4 - 1)^2 + (-1 - 3)^2 ]

   or                     d = √[ (3)^2 + (-4)^2 ]

   or                      d = √(9 + 16) = 5

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
