Draw the line passing through (2, 3) and (3, 2). Find the coordinates of the points atwhich this line meets the x-axis and y-axis.

 4

State whether True or False. Correct that are false

(i) A point whose x coordinate is zero and y-coordinate is non-zero will lie on the y-axis.


(ii) A point whose y coordinate is zero and x-coordinate is 5 will lie on y-axis.


(iii) The coordinates of the origin are (0, 0).
