Question

What is the correct input for determining thedistance between the following two points (7,5) and (-4,7)?

Answer 1

The distance between any two points (x_1, y_1) and (x_2, y_2) is

`d=\sqrt[]{\mleft(x_1-x_2\mright)^2+\mleft(y_2-y_1\mright)^2}`

For our case, the above formula gives

`d=\sqrt[]{(7+4_{})^2+(5-7_{})^2}`

or if we go in reverse

`d=\sqrt[]{(-4-7)^2+(7-5_{})^2}`

which is the fourth choice.
