I dont know how to do this please help and also please explain, thank you:)

284/1000

Step-by-step explanation:

if you look at it like this:

when you have .2, that would equal 2/10 because its 2 tenths

when you have .28 that would equal 28/100 or 28 hundreths since it is greater than 2 tenths

that means with this, it would be .284 or 284/1000 or 284 thousandths because it is larger than both hundreths and tenths.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
