Let's begin by listing out the information given to us:
There are four students: n = 4
Number of students to be selected: r = 2
To calculate the combination of 2 students to be chosen, we use:

Therefore, there 12 possible combinations from these 
 
        
             
        
        
        
area of a circle is PI x r^2
2 = d/2 = 5.4/2 = 2.7 cm
 using 3.14 for PI
3.14 x 2.7^2 = 22.89 square inches
360 degree in a circle, shaded area is 180 degree, which is 50%
 so 22.89 x .5 = 11.45 cm^2
 
        
             
        
        
        
Hello and Good Morning/Afternoon:
<u>Let's take this problem step-by-step:</u>
<u>First off, let's write the line in point-slope form:</u>
   
- (x₀, y₀) any random point on the line
- 'm' is the value of the slope
<u>Let's calculate the slope:</u>
  
- (x₁, y₁): any random point on the line                                     ⇒   (-2, -6)
- (x₂,y₂): any random point on the line that is not (x₁, y₁)         ⇒   (2, -3)
                  
<u>Now that we found the slope, let's put it into the point-slope form</u>
   ⇒ we need (x₀, y₀) ⇒ let's use (2,-3)
      
<u>The equation, however, could also be put into 'slope-intercept form'</u>
      ⇒ gotten by isolating the 'y' variable to the left
            
  
<u>Answer:</u> or
 or 
    *<em>Either equations work, put the one that you are the most familiar with</em>
Hope that helps!
