Question

What is the approximate distance between the points (-5, 1) and (-2, 3) on a coordinate grid? A.7.81 units B.3.61 units C.2.23 units D.3.32 units

Answer 1

The formula for distance between point in a coordinate grid is the following:

$\sqrt{(x2 - x1) {}^{2} + (y2 - y1) {}^{2} }$
Where 1 and 2 stands for the points, so in your case the formula is the following
$\sqrt{( - 2 - - 5) {}^{2} + (3 - 1) }$
$\sqrt{ {3}^{2} + 2 {}^{2} }$
$\sqrt{9 + 4}$
$\sqrt{13} =3.605...$
So your answer is about 3.61
