Which expression could be used to find the distance between point A and point B?
A coordinate plane is shown with point A located at left-parenthesis negative 4 commas 1 right-parenthesis and point B located at left-parenthesis 1 comma 1 right-parenthesis.
$\sqrt{ (1-(-4))^2 + (1-1)^2 }$
To find the distance between point A and point B, you can use the distance formula.
The distance formula is given by:
√((x2 - x1)^2 + (y2 - y1)^2)
where (x1, y1) represents the coordinates of point A, and (x2, y2) represents the coordinates of point B.
In this case, the coordinates of point A are (-4, 1) and the coordinates of point B are (1, 1).
Substituting these values into the distance formula, we get:
√((1 - (-4))^2 + (1 - 1)^2)
Simplifying further:
√((5)^2 + (0)^2)
√(25 + 0)
√25
5
Therefore, the expression to find the distance between point A and point B is 5.
