What is the distance, in units, between A (-1,3) and B (3,5)Round to the nearest hundredth
saul85 [17]

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
