Find an equation for the line of best fit for the table below.

first or last depending how you are rounding the decimal

=> the best fit is the first one

Step-by-step explanation:

y = 2.55x - 2.15 when x = 5 => y = 10.6 approximately 11

y = 3.21x - 1.75 when x = 5 => y = 14.3 cannot equal or approximately  11

y = -2.15x + 2.55 when x = 5 => y = -8.2 cannot equal or approximately  11

y = 1.75x + 3.15 when x = 5 => y = 11.9 approximately 11
