Answer 1

k12?

Answer 2

Yes.

Answer 3

All correct! Way too go.

Answer 4

Thank you...

Answer 5

1 through 3 are incorrect

Answer 6

if you meant to say -5/8 for #4, then you are correct

Answer 7

I was thinking that too but wasn't sure ..

Answer 8

Thank you @jim_thompson5910

Answer 9

y = mx + b
if m is the slope and the equation is the same as y=(1/6)x - 5
the answer is A not B.
2: 6x-3y=4
you have to isolate the y to find this
-3y=-6x+4
y=2x-(4/3)
the slope is 2
3: 15y-3(4y+10)
you distribute the -3 first
15y - 12y - 30
then combine like terms
3y-30
4: for this problem you can use the formula
y_2 minus y_1
divided by x_2 minus x_1
dont forget: (x,y)
(10-5)/(1-9)
so the slope is 5/(-8)
