The statement (A), statement (B), statement (D) are correct because the equation is y = 437.9x + 439.4

<h3>What is the line of best fit?</h3>

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

From the data given, we can calculate the correlation coefficient, slope of the line, and y-intercept.

r = 0.90

Since r is close to 1 shows a strong correlation.

Slope of the line of best fit = 437.9

Y-intercept of line of the best fit = 439.4(Refer to the attached picture)

The line will be:

y = 437.9x + 439.4

Thus, the statement (A), statement (B), statement (D) are correct because the equation is y = 437.9x + 439.4

The first thing we are going to do to graph our equation is solve them for y:
For our first equation:
4x-5y=50
-5y=20-4x
y= \frac{4}{5} x-4
For our second equation:
3x+y=-4
y=-3x-4

Now, we just need to use the graphing utility to graph our equations:
y= \frac{4}{5} x-4
y=-3x-4

We can conclude that the graph of the equations is:

The total amount that Sara spent for her meals during the first week is,
                          $11.52 + $6.48 + $5.99 + $14.00 + $9.50 = $47.49
With an average of $9.498

During the second week, she spent $4 more making her total equal to $51.49. The average is equal to $10.298. The increase in the mean is equal to,
                         increase in mean  = $10.298 - $9.498 = $0.8<span>Comments</span>
