Answer:
The slope is 
Step-by-step explanation:
Take the general equation of a straight line 
Here  is the slope of the line.
 is the slope of the line.
So let's get the equation of the line in the question in the same form.

Add  to both sides:
 to both sides: 
Add  to both sides:
 to both sides: 
Divide by  to get it into the general equation:
 to get it into the general equation: 
Now compare it to the general equation to find the value of  . The value of
. The value of  is the coefficient of
 is the coefficient of  which we can see is
 which we can see is 
 
        
             
        
        
        
To solve this, we need to know how to find the mean of a set of data and how to find the median of a set of data.
To find the mean, or often called the average, we should add all of the values up, and then divide it by the number of values.
588+838+691+818+846+725+605+732+750 = 6593
6593/9=732.556
The problem tells us we should round to the nearest point, so our mean credit score is 733.
To find the median, we need to order the data from lowest to highest and find out which credit score(s) are right in the middle. If there are 2 in the middle, we simply should add them and divide by 2 to get our median. An easy way to do this is after you order them, you simply cross off one on each side until there is only 1 (or 2) left.
588 605 691 725 732 750 818 838 846
       605 691 725 732 750 818 838
              691 725 732 750 818
                     725 732 750
                            732
Since we only have one number in the middle, we are done with the median! We know our median is 732.
Now we simply need to compare them and subtract the lower one from the higher one.
Mean:733
Median: 732
733>732
We know the mean is bigger, so we should subtract the median from the mean.
733=732=1
Using the logic above, we can see that the mean is 1 point higher than the median.
