Since there is no picture, I cannot give you a specific answer, but...
To decide if a line best fits a scatterplot you have to look at whether or not the line even remotely makes sense, if the dots are on one side and the line is no where near any of the dots, it is probably not a realistic placement.
If it looks realistic, take a look at if it best fits the dots, is there a line that would touch more or be nearer to more of the dots?
Well if it is -20 then A but if it was just 20 it would be C all you have to do is divide
0.132 written in lowercase:
one hundred thirty-two thousandths
zero point one hundred thirty-two
or, even simpler:
zero point one three two
B) because if you round your numbers, -18 1/4 is -18 and 2 2/3 rounds up to positive 3
Sum means u add the two numbers together
38 + 27 = 65
