Answer:
Step-by-step explanation:
3x+y-12=0
3x+y=12
3x=12-y
x=(12-y)÷3
let y = 0, x = (12-0)÷3= 12÷3= 4 => x=4,y=0 => (x,y) = (4,0)
x-3y+6=0
x-3y=-6
x= -6+3y
let y=1, x= -6+3*1 = -6+3= -3 => x=-3,y=1 =>(x,y) = (-3,1)
Now, plot the points and join them then shade the region that is bounded to x axis
thank you !!!
hope u are satisfied and pls do rate!!1
