Explanation:
The x cordinate of a point can ve found if we draw a vertical line from the point to the x axis. Same foes for the y coordinate and y axis.
So the x coordinate of P is c.
Also two points that belong in the same vertical line in one of the two axis have the same respective coordinate. Here points (a, b) and P both belong to the same vetical line to the y axis. So they have the same y coordinate, b.
So we get that the coordinates of P are:
(c, b)
