is the correct answer and this expression can be simplified to find the slope of the line of best-fit in the scatterplot below by using the the slope equation : 
.
What is Slope of the Line?
The slope of the line is the measure of its steepness and direction. Without using a compass, determining the slope of lines in a coordinate plane can help predict whether the lines are parallel, perpendicular, or none at all.
Any two distinct points on a line can be used to calculate the slope of that line. The slope of a line formula computes the "vertical change" to "horizontal change" ratio between two distinct points on a line. In this article, we will learn about the slope-finding method and its applications.

The measures give the description of the shape and the whisker plot from the data. The median is always placed in the middle of the center.
<h3>What is a graph?</h3>
A graph is the diagrammatical representation of the data or information set that are illustrated in the form of vertical and horizontal coordinates.
The data given shows:
- Mean = 39,500
- Median = 20000
- Mode = 23000
- Minimum = 15,000
- Maximum = 255000
The whisker plot and the box shape are attached as an image below.
From the image, it can be seen that whiskers are at the right and left of the box, and the box initiates from the lower quartile to the upper quartile.
The median of the data is at the middle, the maximum is at the end of the right whisker, and the minimum is at the end of the left whisker.

Answer:
According to the passage, women’s style of communication has often involved understanding other's emotions.
Explanation:
Answer:
T-Shirt Cost = £7
Hat Cost = £3
Explanation:
Important Information:
4 t-shirts and a hat costs £31.00
2 t-shirts and a hat costs £17.00.
Here we assume t-shirt be x and hat be y.
Explanation/Solution:
Based on the above information, the calculation is as follows:
4x + y = 31
2x + y = 17
Now subtract equation 2 from 1
2x = 14
x = 7
So y is
4(7) + y = 31
28 + y = 31
y = 3
Therefore we can conclude that The t-shirt cost £7 and Hat cost £3.
