Identify the ordered pair that represents the vector from a (1,6) to b (2,-3) and the magnitude of ab

Answer: magnitude ab = 9.06

Step-by-step explanation:

The vector coordinates will be represented with (X, Y)

Magnitude of ab will be

ab^2 = (X2 - X1) ^2 + (Y2 - Y1) ^2

ab^2 = (2 - 1) ^2 + (-3 - 6) ^2

ab^2 = 1^2 + 9^2

ab^2 = 1 + 81

ab = 9.06
