The points A and B are marked on the diagram.
Two points are on x-y axis
Showing two points A and B on x-y axis having co-ordinates
(a) Write as a column vector.
(b) . Write down the co-ordinates of C.
Explanation
Here, as shown in figure,
(a) Here, Point A = (2, 3) and point B = (3, -4)
So, for vector of , so as a column vector:
(b) Here, , so as a row vector we can write as (-5, -2), let take co-ordinate of C = (x, y) and B (3, -4) is given.
So,
So, C (x, y) = C (-2, -6)
