Hello,
Please, see the attached file.
Thanks.
The first decimal point is tenth. 4.88
when rounding, we just look at the number right after the number you want to round to. it's 8 right? since 8 is closer to 10 than 0,
we round it to 4.9
(4.8 + 0.10)
Intercepts X = (-1,0) And Intercepts Y = (0,-1)
It’s a because when you flip it will be A
