Signs of the Coordinates of a Point

The number 3,4,5 can be (A) direction cosines of a line in space (B) direction numbers of a line in space (C) coordinates of a point on the line y=4z=0 (D) coordinates of a point in the plane x+y-z=0

Seg AB is parallel to the Y-xais and coordinates of the point A are (1,3) then coordinates of the point B each can be _ _ _ _ _ _ _ _

Point P is the centre of the circle and AB is a diameter . Find the coordinates of point B. If coordinates of point A and Pare (2,-3) and (-2,0) respectively .

See Fig.3.14. and write the following:(i) The coordinates of B.(ii) The coordinates of C.(iii) The point identified by the coordinates (3,\ 5) .(iv) The point identified by the coordinates (2,\ 4)dot (v) The abscissa of the point D. (vi) The ordinate of the points H. (vii) The coordinates of the points L. (viii) The coordinates of the point M.

In Fig 4 the coordinates of point D are

Find the equation of a curve passing through the point (0," "2) given that at any point (x, y) on the curve, the product of the slope of its tangent and y coordinate of the point is equal to the x coordinate of the point.

Find the polar coordinates of the points whose cartesian coordinates are (-2, -2)
