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
Plotting the scatter plot and regression line in Excel, the following is generated which is attached further below.
The regression line is,
Comparing it with the general slope-intercept form ,
We are given with a table that projects data on people visiting a landmark for over one week. In this case,the slope of the line of the graph can be obtained by plotting the data in Excel. Through excel, the equation of the line is y = 2.3571x + 120.14 with r2 = 0.82. hene the answer is close to C 2.4
Since there are 60 seconds in one minute, we can write this as 146,000 inches per minute. Since there are 60 * 60 = 3600 minutes in one day, we can write it as 525,600,000 inches per day. Since there are about 63360 inches in one mile, the answer is about 8295 miles per day.
