Question

what is the equation of the line of best fit for the following data round the slope and y intercept of the line to three decimal places

Answer 1

Answer:

A. y = 0.894x +0.535

Step-by-step explanation:

A graphing calculator or spreadsheet can do the computation for you, as in the attached.

_____

The x- and y-values of the data set almost agree, so the slope will be near +1. Selection A is the only choice that matches that assessment.

Answer 2

Answer:

A) y = 0.894x + 0.535

Step-by-step explanation:

We can us a graphing calculator for this.  We will enter the values for x into one list and the values for y into the second list.  We graph the scatter plot and then run the regression.  When we do this, we get

y = ax + b

a = 0.89370078

b = 0.53543307

Rounding to 3 decimal places, we have a = 0.894 and b = 0.535.
