Geometry Graphing - Find missing coordinate when given length of line segment
Hello, I have been struggling with this particular question I feel like I know it I'm just fighting myself on which formula to use.
The questions state: Line segment AB is 2 to the square root of 10, where A has the coordinates (-3, 4) and B has coordiantes (-1, k) Find the value of K.
so I found that AB is 6.32? I'm assuming it is rounded down to 6.
Any help would be greatly appreciated.
