Answer:
Step-by-step explanation:
<u>Slope intercept form:</u>
<u>Use two points from the graph:</u>
<u>The first point is the y-intercept: </u>
<u>Find the slope using the slope formula:</u>
- m = (y2 - y1)/(x2 - x1)
- m = (-9 - (-8))/3 = -1/3
<u>The equation is:</u>
 
        
             
        
        
        
$990 
550 x .80 = 440
$550 + $440 = $990
        
             
        
        
        
Answer:
Step-by-step explanation:
(0, 3)  (5, 1)
(1-3)/(5-0) = -2/5 is the slope
 
        
                    
             
        
        
        
To find 86% of 50, you do 50*.86 (because .86 is the decimal form of the percentage 86%)
50*.86=43 people
Hope this helps
