Taking 1cm = 1 uni
Plotting equation 3x+y+5=0
Let y = 4 then,
=>3x+4=-5
=>3x=-9
=>x=-3
One point is (-3, 4)
Let y=1 then,
=>3(1)+y+5=0
=>y=-8
Other point is (1, -8)
Plotting equation 3y-x=5
Let y=2
=>3(2)-x=5
=>x=1
One point is (1.2)
Let x=-5 then,
=>3y-(-5)=5
=>y=0
Other point is (-5, 0)
Plotting equation 2x+5y=1
Let x=-2 then,
=>2(-2)+5y=1
=>5y=1+5
=>y=1
One point is (-2, 1)
Let y=-1 then,
=>2x+5(-1)=1
=>x=3
The other point is(3, -1)
The point of tge intersection (-2, 1) and the lines given by the equations are concurrent..
