3 Line AB is shown on this coordinate grid.

Coordinate grid with x from -6 to 10 and y from -4 to 10 showing a straight line through B at (-2, -3) and A at (4, 9)
(a) Write down the coordinates of
(i) point A, [1]
(ii) point B. [1]
(b) Plot point C on the grid at \((7, {}^{-}2)\). [1]
(c) The equation of line AB is \(y = 2x + 1\).
A line parallel to AB goes through the point \((0, 4)\).

Write down the equation of the parallel line. [2]
