Question

24. Graph of y = x and y + x = 0 is
please help me through a graph​

Answer 1

Equation : y = x

Keeping x = 1 , 2 and 3 once

y = 1 , y = 2 and y = 3.

Coordinates are : ( 1, 1 );( 2, 2 );( 3, 3 )

Equation, y = - x

Keeping y = 1 , 2 and 3

1 = - x , 2 = - x and 3 = - x

Coordinates are : ( - 1, 1 );( - 2, 2 );( - 3, 3 )

On plotting both equations we get,

That two equation intersect at coordinate (0,0) i.e. origin.

Have great future ahead!
