Solve each of the following systems of equations graphically:
3x+y+1=0,2x−3y+8=0.
From above graph we can see the solution is x=-1,y=2
Solve each of the following given systems of equations graphically and find the vertices and area of the triangle formed by these lines and the y-axis:
2x−3y+6=0,2x+3y−18=0.
3x+2y=4,2x−3y=7.
