Answer:
1) 2,6,18,54,162,468 (multiply by 3 each time)
2) 2, -4, 8, -16, 32, -64 (i'm not sure what this is but i'm pretty confident i'm right lol)
3) 1,3,5,7,9,11 (add 2 each time)
4) 1, 2/3 , 4/6 , 8/9 , _ _ (i'm sorry i tried my hardest but i don't know this one)
Step-by-step explanation:
hope this helped! so sorry about 4...
==> 7x - 4 = 3 + 8x
==> 8x - 7x = -4 - 3
==> x = -7 [ Ans ]
Answer:i think you have to equal them to each other
y=2/3x+4. 4 is the y intercept. 2/3 is the slope. y=mx+b where m is the slope and b is the y intercept
