What is the distance between the points (1, 25) and (4, 21)

Answer 1

Hello!

To find the distance between the points (1, 25) and (4, 21), you need to use the distance formula.

The distance formula is: $d =\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$. With the distance formula, you have to assign the ordered pairs before substituting them into the formula, which is also used to to find the slope of functions.

$d =\sqrt{(21-25)^{2}+(4-1)^{2}}$

$d =\sqrt{(-4)^{2}+(3)^{2}}$

$d=\sqrt{25}$

$d=5$

Therefore, the distance between the two points is 5 units.
