Ques.) Write the equations of the lines p and r in following graph :


A student answered equation of line 'q' as x + y = 1. Did he answer correctly ? Also, find the area enclosed between lines p, q and r.

Dear student
The equation of line p is x =-1and The equation of line r is y=-2Now, the line q passes through the point (1,0) and (0,1) is y-0x-1=1-00-1y=-x+1x+y-1=0Area of triangular region enclosed by p,q,r=12×base×height=12×4×4=8 sq units
