Question: The distance d of a point PP to the line through points AA and BB is the length of the component of APAP that is
The distance d of a point PP to the line through points AA and BB is the length of the component of AP−→−AP→ that is orthogonal to AB−→−AB→, as indicated in the diagram.
So the distance from P=(−2,4) to the line through the points A=(−5,0) and B=(−3,−3) is
P
