@misty1212

Answer 4

i don't think it goes UP

Answer 5

then down by 4.5?

Answer 6

yes, so slope is \(-4.5\)
what is the y intercept this time?

Answer 7

1

Answer 8

hm no
what is y where x = 0?

Answer 9

0

Answer 10

yes so \[y=mx+b\] again
this time \(m=-4.5\) and \(b=0\)

Answer 11

what do you get?

Answer 12

then down by 4.5?

Answer 13

f(x)=-4.5x+0

Answer 14

lol yea but don't write the \(+0\) out at the end or your teacher will think you are a moron

Answer 15

so just f(x)=-4.5?

Answer 16

no \[f(x)=-4.5x\]

Answer 17
