Question

Find the distance between (-2, -3) and (-5, 1).

Answer 1

It's 5.
this involves the Pythagoras theorem formula; a^2 + b^2 = c^2
the legs are 3 and 4 units long (a and b)
so 3^2 + 4^2 = c^2
Where c is the distance you're looking for, more commonly known as the hypotenuse.
so 9 + 16 = 25
the square root of 25 is 5. :)
so 5 is the distance between (-2, -3) and (-5, 1)
