Answer:
hydrogen ion increases
Step-by-step explanation:
as the pH value decreases, the molecule becomes more acidic in nature. and a solution can be termed base when it contains OH-, and an acid when it contains a H+ ion.
the now formed solution will have attained 9 more H+ ions
Answer:
16
Step-by-step explanation:
The standard form equation of the line connecting the two points is 
Linear equation in a standard form is given as 
where,
A, B, and C are constants or numbers
x and y are the variables.
To solve this problem, the following steps would be taken:
Step 1: Find the slope of the line connecting points (-3,4) and (2,-6)

where,

Substitute

Step 2: Find the y-intercept (b) of the line by substituting
and
into
(slope-intercept form)

Step 3: Write the equation of the line in slope-intercept form by substituting
and
into 

Step 4: Rewrite the equation in standard form 

Add
to both sides

The standard form equation of the points (-3,4) and (2,-6) is

Expand the left side:
3x-18 = 10x + 3
Subtract 3x from each side:
-18 = 7x + 3
Subtract 3 from each side:
-21 = 7x
Divide each side by 7 :
<u>-3 = x</u>
