Consider the point P(−5,7) in the Cartesian plane.
(i) Find the equation of the vertical line that passes through P.
(ii) Find the equation of the horizontal line that passes through P.
(iii) Determine the coordinates of the point where the horizontal line obtained in part (ii) meets the y-axis.
(iv) Determine the coordinates of the point where the vertical line obtained in part (i) meets the x-axis.
