Answer 2

(4,0)

Answer 3

Set x= 0 to get y and vice versa for each equation.

Join the points up.

Answer 4

2x+3y=8
-x+ y=-4 Multiply by two

2x+3y=8
-2x+2y=-8 Cancel the x's (2x-2x), add the y's and the integers

5y = 0 therefore y = 0

if y = 0 then:
2x+3(0) = 8
2x = 8
x = 4, y = 0
(4,0)

Answer 5

U want to graph it, right?

Answer 6

thansk what about this one x-2y=4
4x+2y=6

Answer 7

Try the same thing as I did before, just with the new equation. Post the answer you get.
