The table shows the cost of the lunch special for selected years since a diner opened. What is an approximate equation for the line of best fit?
How accurate is the line of best fit? Let 1997 = 0.
(Year)| (cost)
1997 | $6.95
1999 | $7.95
2001 | $8.00
2003 | $8.00
2005 | $9.25
2007 | $ 9.50
A. y = 7.08% +0.24; x is years since 1997;y is cost of the lunch special. Since r = 0.94, which is close to 1, the line of best fit is quite inaccurate.
B. y=0.24x +7.08; x is years since 1997; y is cost of the lunch special. Since r = 0.94, which is close to 1, the line of best fit is quite accurate.
C. y=0.24x + 7.08; y is years since 1997; x is cost of the lunch special. Since r = 0.24, which is close to 1, the line of best fit is quite inaccurate.
D. y = 7.08x + 0.24;y is years since 1997; x is cost of the lunch special. Since r = 0.24, which is close to 1, the line of best fit is quite accurate.

Without any equipment, you can see stars that are 2{,}800{,}0002,800,0002, comma, 800, comma, 000 light-years away. by looking through a small telescope, you can see stars that are 3{,}112{,}000{,}0003,112,000,0003, comma, 112, comma, 000, comma, 000 light-years away. approximately how many times as far can you see using a small telescope as without any equipment?
