What is the equation of the line best fit for the following data? Round the slope and y-intercept of the line to three decimal p

kari74 [83]

Answer:

$y=1.383x-1.526$

Step-by-step explanation:

The given data table is

x : 4 7 10 12 13

y : 5 7 12 14 18

We need to find the equation of the best fit line.

The general form of a best fit line is

$y=mx+b$ .... (1)

where, m is slope and b is y-intercept.

$m=\frac{\sum_{i=1}^nx_iy_i-n\overline{x}\overline{y}}{\sum_{i=1}^nx_i^2-n\overline{x}^2}$

$b=\overline{y}-b\overline{x}$

Using the graphing calculator we get

$m=1.38321\approx 1.383$

$b=-1.52555\approx -1.526$

Substitute m=1.383 and b=-1.526 in equation (1).

$y=1.383x-1.526$

Therefore, the equation of best fit line is $y=1.383x-1.526$ .
