250.6 is your number
The "6" in .6 right after the decimal is the tenths place
So right after the tenths place is the hundredths place
But as you can see in 250.6, there is no hundredths place you can see so it is 0
250.60 is the same as 250.6
So 250.6 is already rounded to the nearest hundredths
Y+6=7/1(x-6)
y=7/1x-48
hope that helps!
