The distance between two points on a graph is
Square root of [ (difference in the y-values)² + (difference in the x-values)² ] .
So for these two points, the distance between them is
square root of [ (-5)² + (12)² ] =
square root of [ 25 + 144 ] =
square root of [ 169 ] =
13 .
Yes, the ' 13 ' you typed at the end of the question is the correct answer to it.
