Q.1= DRAW THE GRAPH 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 .Calculate the area bounded by these lines and x axis.

 

Hi Vaibhav!
Here is the answer to your query.
 
Three solutions of the equation x + y + 1 = 0 are given as
 
 
 
Area of the required triangle = area ABC = (1/2)×AB×CM = (1/2)×5×15 = 37.5 sq units
 
Hope! This will help you.
Cheers!
