Answer:
Because Water is not a buffer solution and the acetic acid/acetate solution is a buffer solution. An acidic buffer is a solution of a weak acid (acetic acid) and its conjugate base pair (sodium acetate) that prevents the pH of a solution from changing drastically through the action of each component with incoming acid or base.
 
        
             
        
        
        
 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.

Based on the computation done, the value of the combined gross monthly income is $7630.
Since there are four weeks in a month, Joe's income will be:
= 23.50 × 40 × 4
= 3760
The value of Zola's income will be:
= 21.50 × (40 + 5) × 4
= 21.50 × 45 × 4
= 3870
Therefore, the combined gross monthly income will be;
= $3760 + $3870
= $7630
