Find the equation of the line of best fit for the points (-3,-40) (1,12) (5,72) and (7, 137) a. y = 3x + 17 b. y = 17x + 3 c. y = 3x + 1 d. y = x + 3

Try this option:

the best one is B. y=17x+3

P.S. it is possible to check, if to substitute the coordinates of given points (for example, (-3;-40), result is (-3;-48))

B.  y = 17x + 3

Step-by-step explanation:

Here, the given points,

(-3,-40) (1,12) (5,72) and (7, 137),

Since, the equation of a line is,

y = ax+ b

Where,

By the graphing regression tool,

We get,

a = 16.9237 ≈ 17,

b = 2.94068 ≈ 3

Hence, the line of best fit would be,

OPTION B is correct.
