Please show your work and exactly where you are stuckvanbinark said:(x,2) (-2,y) (x,3)

Solve 1/2x + 3y = 6 for the 3 points to graph

1/2x + 3(2)=6

1/2x + 6 = 6

-6 -6

-------------------

1/2x = 6

________

1/2 1/2

x = 3

(3,2)

1/2x + 3y = 6

1/2(-2) + 3y = 6

-1 + 3y = 6

+1 +1

--------------------

3Y = 7

---------

3 3

Y = 7/3

(-2,7/3)

1/2X + 3Y=6

1/2X + 3(3) =6

1/2X + 9 = 6

-9 -9

----------------

1/2X = -3

-------------

1/2 1/2

X = -6

-------------------

1/2x = 6<----IncorrectThis should be 1/2 x = 0

________

1/2 1/2

x = 3

(3,2)<----This should be (0,2)

1/2x + 3y = 6

1/2(-2) + 3y = 6

-1 + 3y = 6

+1 +1

--------------------

3Y = 7

---------

3 3

Y = 7/3

(-2,7/3)Correct....You can check it yourself by putting these values back into the function (1/2*x + 3*y) and see if you get '6' as answer.

1/2X + 3Y=6

1/2X + 3(3) =6

1/2X + 9 = 6

-9 -9

----------------

1/2X = -3

-------------

1/2 1/2

X = -6

(-6,3)<---------Now you check your answer and find out if you are correct or not.
