Question

40. Represent the following pair of equations graphically. Shade the triangle formed by
these lines with Y axis. Also write the coordinates of the triangle so formed and
calculate its area. x + 3y = 6 & 2x-3y
12​

Answer 1

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 = 1/2×4×6

=12 units.
