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

Answer 1

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.

Answer 2

I think the slope is 5 - can someone please double check this for me?

Answer 3

Can anyone help me please?

Answer 4

two points are (1,30) and (7,55)

apply the slope formula

Answer 5

y2 - y1 divided by x2-x1 = (55-30)/(7-1) = ?

Answer 6

ok so 4.16 and rounded to the nearest tenth is 4.20?
