The line of best fit drawn on the plot shown is used to predict the number of tickets sold on a certain day. Use the two points shown on the line of best fit to calculate its slope to the nearest tenth.

The two most identifiable points  are   ( 1, 30)  and ( 7, 55 )

 

Slope  =  

 

[ subtract the y coordinates in some order ] / [ subtract the x coordinates in the same order ]

 

[ 55 - 30 ]  / [ 7 - 1 ]   =

 

25 / 6   ≈  4.2
