In order to determine the distance in between the given points, use the following formula:
d = √((x1 - x2)² + (y1 - y2)²)
where, for this case, (x1,y1) = (-1,3) and (x2,y2) = (3,5).
Replace the values of the parameters:
d = √((-1-3)²+(5-3)²)
d = √((-4)²+(2)²)
d = √(16+4)
d = √20
d = 4.47
Hence, the distance in between A and B is 4.47 units
