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.
