Y = -4x + 8 
First you need to find the slope of the line.
The slope formula is m = y2-y1/x2-x1
If you plugged in the points it would be m = -4-4/3-1
so m = -8/2 = -4
so the slope is -4
now we need to write the equation of the line
for this u use point slope form
the formula for that is y-y2=m(x-x1)
so if you plug it in it would be:
y-(-4)=-4(x-3)
now you solve
y+4=-4x+12
y+4-4= -4x+12-4
y = -4x + 8
and now you have the slope of the line
I hope this helps! :)
        
             
        
        
        
Well, is namely their difference, so, let's first convert the mixed fractions to "improper", and subtract.

Answer:
27
Step-by-step explanation:
total=average ×no.
18×40=720 the no. of coins for all children
12×24=288 no. of coins for boys
720-288=432 for all girls
one girl, mean,divide 432 by 16= 27
