Answer:

No, order in which we subtract the x coordinates and y coordinates does nor matter

Explanation:

Let the two points be
\left ( x_1,y_1 \right )\,\,,\,\,\left ( x_2,y_2 \right )

By distance formula: distance between points
\left ( x_1,y_1 \right )\,\,,\,\,\left ( x_2,y_2 \right ) is equal to
√(\left ( x_2-x_1 \right )^2+\left ( y_2-y_1 \right )^2)

We know that
\left ( x_2-x_1 \right )^2=\left ( x_1-x_2 \right )^2 and
\left ( y_2-y_1 \right )^2=\left ( y_1-y_2 \right )^2

So,


√(\left ( x_2-x_1 \right )^2+\left ( y_2-y_1 \right )^2)\\=√(\left ( x_1-x_2 \right )^2+\left ( y_1-y_2 \right )^2)

Therefore, we can say in distance formula , order in which we subtract the x coordinates and y coordinates does nor matter .

For example distance between points
\left ( 2,3 \right )\,,\,\left ( 4,5 \right ) is shown as below :


√(\left ( 4-2 \right )^2+\left ( 5-3 \right )^2)\\=√(\left ( 2-4 \right )^2+\left ( 3-5 \right )^2)\\=√(4+4)\\=√(8)

use the first x then subtract the second x. then the y then the second y. yes it does matter because the numbers you subtract will add up to your answer
