Question

Draw the graph of the equation 3x+y = 7 y =0 and x= 7 solution of this equation from the graph.Shade the portion bounded by the line and both the axes.

Answer 1

Answer:

x+3y=6⇒ when  x=0y=2⇒(0,2)

                         when  y=0x=6⇒(6,0)

2x−3y=12⇒x=0y=−4⇒(0,−4)

                             y=0x=6⇒(6,0)

Are of shaded part =21×4×6

                                 =12 units.
