Class 11 || Basic of Coordinate Geometry || IIT-JEE || Board Exams

If vec a is a position vector whose tip is (1,-3)dot Find the coordinates of the point B such that vec A B= vec a , if A has coordinates (-1,5)dot

If(-4,3) are the coordinates of a point P in the new system when the origin is shifted to (1,5), then find original coordinatres of P.

If the points A(1,2) , B(0,0) and C (a,b) are collinear , then

Examine whether the points are collinear or not: (1,5),(2,-4),(3,3)

P, Q and R are three collinear points. P and Q are (3, 4) and (7, 7) respectively, and PR =10 units. Find the coordinates of R.

Statement : Points (1, 1), (2, 3), and (3, 5) are collinear.

Show that the points (1, 1), (2, 3) and (5, 9) are collinear.

The points A(-3, 2), B(2, -1) and C(a, 4) are collinear. Find a.
