Multiply 2nd equaton by 4 and add to first
-9x+4y=8
<u>-12x-4y=16 +</u>
-21x+0y=24
-21x=24
divide both sides by -21
x=-24/21
x=-8/7
C is answer
I’m very confused! Is this a math problem!?
Answer:
-5/7
Step-by-step explanation:
Find the change between the two x values, which is seven
Find the change between the two y values, which is -5
With slopes, the y always goes over the x, making your answer -5/7
B false ( I think that is the answer )
