Answer:
about 465 students do not prefer non-fiction
Step-by-step explanation:
first I labeled each section on the pie the
the blue area looks like the smallest so that's most likely 60 students
then orange is 75 students
dark blue is the biggest so its 180 students 
gray and yellow are the last ones left and gray is bigger than yellow so gray is 150
the number of students that prefer non-fiction is 100 so you add all the other number to get how many students don't prefer non-fiction=465
I hope this helps and makes sense ;D
 
        
             
        
        
        
Any two angles whose sum is 180 degrees are supplementary.
Supplementary angles are a pair of angles that add up to 180 degrees.
hope this helps

The answer to this is 27/8 :)
 
        
                    
             
        
        
        
A) Slope = 5, for the y intercept plug 0 into x, so y=5(0)+10 =10. So the y-intercept is (0,10)
c) I added the graph below. First you plot the y intercept, (0,10). Then count 5 up and 1 right and plot a point because the slope is (5/1) "slope is easy and fun, rise over run." You can go the opposite way too, 5 down and 1 left and then plot a point. Plot 5-7 points. The x-axis is time, because that is the independent variable and the y-axis is baskets of berries because that is the dependent variable.
