2x - 2y = 6
3x + 2y = 9
Solve the system of equations.
A) x = 0, y = 3
B) x = 3, y = 0
C) x = 1, y = -2
D) x = -2, y = 1

B) x = 3, y = 0

Step-by-step explanation:

I will use the subtraction method, at least i think it is the subtraction method lol:

2x - 2y = 6

3x + 2y = 9

1: Combine

5x=15

x=3

2: Substitute

2(3)-2y=6

6-2y=6

-2y=0

y=0

3: Check by pluggin answers in

2(3)-2(0)=6

6-0=6

6=6 true

3(3)+2(0)=9

9+0=9

9=9 true

DISCLAIMER: the answers might not be right, so you should check just in case and i hope this made sense, you can ask questions too.

also... i would be great if i got a brainliest because i need one more to level up but you don't have to bc i bet someone has a better explanation hehe

a is the correct

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
