The scatter plot below shows the number of prom tickets sold over a period of 7 days.the scatter plot below shows the number of prom tickets sold over a period of 7 days.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.slope =  a0

The slope of the line to the nearest tenth is:

                             4.2

Step-by-step explanation:

Clearly after looking at the scatter plot we observe that the line of best fit passes through the points:

(1,30) and (7,55)

We know that the slope of any line passing through two points (a,b) and (c,d) is calculated by the formula:

Here we have:

(a,b)=(1,30)   and   (c,d)=(7,55)

Hence, the slope is:

Hence, the slope of the line of best fit is:

                     4.2
