Question

Find the difference between points P (4,6) and Q (8,9)

Answer 1

`distance = √(x2 - x1 + y2 - y1) \\ here \\ \: \: \: \: x1 = 4 \\ \: \: \: \: x2 = 8 \\ \: \: \: \: y1 = 6 \\ \: \: \: \: y2 = 9 \\ now \: we \: have \: to \: substitute \: the \: given \: values \: in \: the \: above \: formula \\ we \: get \\ \: \: \: \: \: \: = √(8 - 4 + 9 - 6) \\ \: \: \: \: \: \: = √(4 + 3) \\ \: \: \: \: \: \: = √(7) \\ \\ hope \: it \: helped`
