Draw the graphs of x =0, y =0,x=a,y=b

Answer

54 sq units

Explanation

(i) Given equation is x = 0 i.e 1.x+0.y=0
`rArr` x=0-0.y
Let y=0 `rArr` x=0
Let y=1 rArr x=0
Let y =2 `rArr` x=0
Let y =-1 `rArr` x=0
Table for values :

Plot the points O (0,0) , A(0,1), B(0,2),C(0,-1) on the same graph paper and join them.
So , always remember that x =0 is the equation of y axis (as all these points lie on y axis)

(ii) Simi,lary we can plot the points for y = 0 i.e 0x+1y=1, and plot these points on the graph paper we find that y =0 is the equation of x - axis.
(iii) for x =a i.e x+0.y=a `rArr` x=a-0.y
Let y =0, x=a
Let y =1, x=a
Let y =2, x=a
Let y=3,x=a
Tables for values:

Plot the points A(a,0),B(a,1),C(a,2),D(a,3) on the same graph paper and join them. so , always remember that x = a is the equation of straight line parallel to ya axis at a distance of 'a' units form the origin (as all points on its satisfy is equation)
(iv) Similary we can plot the points for y = b i.e 0, x+1 .y =b and plot these points on the graph paper we find that y = b is the equation of a straight line parallel to x axis at a distance of 'b' units from the origin . some points on this line are `A_(1)(0,b),B(1,b),C_(1)(2,b), D_(1)(3,b)`
