Answer 2

You can calculate the distance between two points A (-2, 1) and B (1, -4) using the distance formula, which is derived from the Pythagorean theorem. The distance formula is:

$d = \sqrt{(x2 - x1)^2 + (y2 - y1)^2}$

Where (x1, y1) are the coordinates of point A, and (x2, y2) are the coordinates of point B.

In this case:

$x1 = -2$ $y1 = 1$ $x2 = 1$ $y2 = -4$

Plugging these values into the formula:

$d = \sqrt{(1 - (-2))^2 + (-4 - 1)^2} = \sqrt{(1 + 2)^2 + (-4 - 1)^2} = \sqrt{3^2 + (-5)^2} = \sqrt{9 + 25} = \sqrt{34}$

So, the distance between points A (-2, 1) and B (1, -4) is $\sqrt{34}$ units.
