So I am assuming that there is a 20% off sale on an item that is 20$.
Edit: I read the question wrong, the 2nd thing I wrote down is the correct answer, it will be $24 after the markup.
Given
The graph of the infant mortality rate and life expectancy is given in the scatter form.
Explanation
To determine the relation between the life expectancy and infant mortality rate ,
use the given graph.
From the graph given, it is clear that as the infant mortality rate increases then the life expectancy decreases.
Therefore, the countries with high mortality rates tended to have shorter life expectancies.
Answer
Hence the correct option is B.
Answer:
y = -2x -9
Step-by-step explanation:
<h2><u>in order to solve this question you have to do the following : </u></h2>
1. find the midpoint of the coordinates given
2. find the gradient of the line
3. make the equation
<h3><em><u>STEP : The midpoint </u></em></h3>
formula of the midpoint is

now place the values in the equation :

midpoint = ( -3 , -3)
<h3><em><u>STEP 2 : The gradient </u></em></h3>
formula of finding the gradient

insert the values in the equation:

=
gradient = -2
<h3><em><u>STEP 3: Form the equation </u></em></h3>
use the formula of the equation :

now make use of the gradient(m) and the midpoints and insert into the equation
(y-(-3)) = -2(x -(-3))
hence
y+3 = -2 (x +3)
y= -2x -6 -3
<h3><u /></h3><h3><u>y = -2x -9 </u></h3>
