Draw the graphs of `x-y+1=0` and `3x+2y-12=0` . Determine the coordinates of the vertices of the triangle formed by these lines and x-axis and shade the triangular area. Calculate the area bounded by these lines and x-axis.

Explanation

`x-y+1 =0->Eq(1)`

If we put,` x=0`, then ` y = 1`

If we put `y=0` then `x=-1`

So, we can draw aline with points (0,1) and (-1,0).

Please refer to video for graph.

`3x+2y-12=0->Eq(2)`

If we put,` x=0`, then ` y = 6`

If we put `y=0` then `x=4`
