Plot the following points and draw a line through the points.

(0, 7), (4, –4)

Let the points be P (0, 7) and Q (4, -4)


Consider P


x co-ordinate = 0


y co-ordinate = 7


as x = 0 the point P lies on the Y-axis because it is 7 units above the X-axis and 0 units to the left or right from the Y-axis


Consider Q


x co-ordinate = 4


y co-ordinate = -4


point Q is 4 units to the right of Y-axis and 4 units below Y-axis
