Answer 2

y=mx+b You have y and x and b is the slope. so first fill that in..

Answer 3

y = -2x + b and thats how far i have got

Answer 4

plz help asap i need it

Answer 5

y=12
x=8
12=-2(8)+b

Answer 6

So now to find b which is y-intercept. Just turn the problem around and have b alone on one side and then solve.

Answer 7

ok hold on

Answer 8

-4?

Answer 9

i have calculator with me :P

Answer 10

then just right it in slop-intercept form. y=mx+b

Answer 11

wait how'd you get -4?

Answer 12

brb

Answer 13

12=-2(8)+b
add 2 to both sides
14=(8)+b
subtract 8 from both sides
6=b
