Line of Fit Equation

Is this line an accurate line estimate of best fit for the data?

• Yes

• No

The linear model to represent the distance (in miles) traveled given the time (in hours) driving is  m=-1.79+61.93h. Predict how far a person will travel driving 10 hours. 

• 617.51 miles

• 621.09 miles

• 100 miles

• 0.19 miles

Which of the following lines represents the line of best fit for the scatter plot?

• A

• B

• C

• D

Find the equation of the line of best fit for the given data

• y = 163.41x+1.49

• y =- 163.41x+ 4.19

• y =- 4.19x+163.41

• y = 4.19x -163.41

Find the equation of the line of best fit for the given data

• y=163.41x+4.19

• y=-163.41x+4.19

• y=-4.19x+163.41

• y= 4.19x+(-163.41)
  

What is the equation of the line of best fit

• y= -2x + 10

• y= 10x+ 2

• y= 10

Is this line an accurate line estimate of best fit for the data?

• Yes

• No

Which scatter plot shows a linear relationship between x and y?

• Graph A

• Graph B

• Graph C

• Graph D

Select the statement that best describes the line.

• The line is the line of best fit.

• The line is NOT a line of best fit because it does not pass through two points.

• The line is NOT a line of best fit because it does not go through the middle of the data set.

• The line is NOT a line of best fit because it does not go through the origin.

What is the equation of the line of best fit?

• y= 6x + 2

• y = -2x +6
