The option (B) d = StartRoot (0 minus (negative 2)) squared + (0 minus (negative 4)) squared EndRoot can be used to determine the distance between the origin and (–2, –4)
Co-ordinates
Co-ordinates are distances or angles, represented by numbers, that uniquely identify points on surfaces of two dimensions (2D) or in space of three dimensions ( 3D )
What are steps to solve this problem?
The steps are as follow:
- According to distance formula:
[tex]d=\sqrt{(x_{1}-x_{2} )^{2}+(y_{1}-y_{2} )^{2} }[/tex] where d = distance between two coordinates
- Here we have to distance between origin and (-2, -4)
∴ ([tex]x_{1},y_{1}[/tex]) = (0, 0) and ([tex]x_{2},y_{2}[/tex]) = (-2, -4)
- Putting this value in distance formula, we get:
[tex]d = \sqrt{(0-(-2))^{2}+(0-(4))^{2} }[/tex]
So the equation will be option (B) d = StartRoot (0 minus (negative 2)) squared + (0 minus (negative 4)) squared EndRoot
