A person travels by car.  They record their miles driven in a data table.  Calculate the linear regression equation of this data.

• y = 61.93x - 1.79
• y = -1.79x + 61.93
• y = 0.016x + 0.03
• y = 0.03x + 0.016

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

In slope-intercept form, write the equation of the line passing through the points (-3,4) and (-4,2).

• y = -2x + 10

• y = -2x - 10

• y = 2x - 10

• y = 2x + 10

In slope-intercept form, write the equation of the line passing through the points (-4,1) and (-3,2).

• y = -x + 5

• y = x + 5

• y = x - 5

• y = -x + 5
