Answer:
[tex]\boxed{\boxed{\text{slope}=2.4}}[/tex]
Step-by-step explanation:
A scatter plot is a two-dimensional data visualization that uses dots to represent the values obtained for two different variables one plotted along the x-axis and the other plotted along the y-axis.
A regression line is a straight line that describes how a response variable y changes as an variable x changes. It is the relation between two variables x and y.
Here,
x = day of a week
y = number of visitors
The given data points are [tex](1,120),(2,124),(3,130),(4,131),(5,135),(6,132),(7,135)[/tex]
Plotting the scatter plot and regression line in Excel, the following is generated which is attached further below.
The regression line is,
[tex]y = 2.357x + 120.1[/tex]
Comparing it with the general slope-intercept form [tex]y=mx+c[/tex],
slope = [tex]2.357\approx 2.4[/tex]
