Question

can you use the mean of a x,y table to find the slope and y-intercept or do you have to use rise/run?

Answer 1

yes you can do it

Answer 2

tell me the x y numbers and i will help you :)

Answer 3

Find the equation of the line of best fit from the data in the table. Round the slope and the y-intercept to the nearest hundredth

Answer 4

i did 12+14+16+18+20=80
80/5=16

54+53+55+54+56=272
272/5=54.4

y=mx+b
y=16x+54

Answer 5

Are you sure you are not asked to find the regression line or "the least square fit" line for this data?
