Answer 2

do you know how to work out the equation of a line in point gradient form?

Answer 3

no

Answer 4

okay so use this equation:
(y - {any y coordinate which lies on the line}) = m (x - {the x coordinate that goes with the y coordinate})

note: m is the slope or gradient.
SO sub in your coordinate and slope into that equation first
