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.

The slope is

Step-by-step explanation:

The picture of the question in the attached figure

Let

x ----> the number of days

y ---> the number of tickets sold

we have the points

(1,30) and (7,55)

The formula to calculate the slope between two points is equal to

substitute the given values in the formula

i dont know i just need points

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
