what is the distance between (-5,2) and (-9,2)

Question

anonymous · Answer

The distance between (-5,2) and (-9,2) can be found by using Pythagorean Theorem. just draw it on a graph and connect the points to make a line segment, then you make a right triangle with the line segment. Find the lengths of the sides that share the right angle then use A^2 + B^2 =C^2 then do the squared root of C^2 and you will have the distance between the coordinates.

Thats good to hear :D

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

Its very simple, consider (-5,2) as A and (-9,2) as B where $$x1=-5 , y1=2,  x2=-9, y2=2$$,
now there is a distance formula for straight line i.e $$d=\sqrt{(x2-x1)^2+(y2-y1)^2}$$   $$\sqrt{(-9-(-5))^2+(2-2)^2}$$ $$\sqrt{(-4)^2+0^2}$$ $$\sqrt{16}=4$$
