Respuesta :
6x + 3y = 9
2x + 3y = 1
Subtract the equations from each other.
4x = 8
Divide both sides by 4.
x = 2
Plug in (2) for x in the first equation.
6x + 3y = 9
6(2) + 3y = 9
12 + 3y = 9
Subtract 12 from both sides.
3y = (9-12)
3y = -3
Divide both sides by 3.
y = -1
(2, -1)

Solution 1: 6(x) + 3(y) = 9
Solution 2: 2(x) + 3(y) = 1
________________________
Your graphic organizer↓
3(y) + 6(x) = 9
3(y) + 2(y)= 1
_______________________
For the y-intercept; solution 2 ↓
"2" becomes a negative
3(y) which is equal to -2(x) + 1
Take off the "3" then this becomes y = [tex] \frac{-2(x)}{3} [/tex] + [tex] \frac{1}{3} [/tex]
_________________________________
Moving on to the x-intercept ; the first solution
6(x) + 3 [tex]( \frac{-2(x)}{3} ) + \frac{1}{9} [/tex] = 9
_______________________________
We can simplify to find the x-intercept
4(x) = 8
the x-intercept is 2
______________________________
Lastly, we are looking for the y-intercept
[tex] \frac{-2(x) }{3} + \frac{1}{3} = ? [/tex]
[tex] -\frac{2}{3} (2) + \frac{1}{3} = -1 [/tex]
So, the y-intercept is: -1

Answer↓
[tex] \left \{ {{x=2} \atop {y=-1}} \right. [/tex]
x-intercept: 2
y-intercept: -1
Solution 2: 2(x) + 3(y) = 1
