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.

Answer:
The answer is "9"
Explanation:
In the given-question, the attachment file, which is "graph" is missing. so, in this question, firstly we add the file and then provide the solution:
please find the attachment of the image file.
Solution:
In the given graph by canceling, the out ends for getting the middle median that is equal to 2, that's why its value is equal to "9".
This movement of electrons between atoms is called electrical current.
The concentration of hypochlorite ion if 20.00 ml of bleach requires 32.00 ml of 0.500 m hcl to reach the equivalence point is: 0.800 M.
<h3>
Concentration of hypochlorite ion</h3>
Given:
Ca = concentration/molarity of acid=0.500 M
Va = volume of acid= 32.00 cm3
Cb = concentration/molarity of base=?
VB =volume of base= 20.00 cm3
Hence:
Concentration of hypochlorite ion=0.500 × 0 × 1/ 20.00
Concentration of hypochlorite ion=0.800M
Inconclusion the concentration of hypochlorite ion if 20.00 ml of bleach requires 32.00 ml of 0.500 m hcl to reach the equivalence point is: 0.800 M.
