Answer: The fraction of the fertilizer is left = 
Step-by-step explanation:
Given: Fraction of fertilizer used in first garden = 
Fraction of fertilizer used in second garden = 
Fraction of fertilizer used in third garden = 1- (Fraction of fertilizer used in first garden)-(Fraction of fertilizer used in second garden)
= 

Hence, the fraction of the fertilizer is left = 
Answer:
The slope is -2
Step-by-step explanation:
(0,4) (3,-2)
remeber the equation is Y2-Y1/X2-X1
Y2 = -2
Y1 = 4
X2=3
X1=0
Plug it in the euqation to see if it works
Mid point formula
(x1 + x2) , (y1+y2)
--------- --------
2 2
Thus for x it would be (6+(-2)) /2 or 4/2 or 2.
For y (-4 + 4) / 2 or 0 / 2 or 0.
Mid point is (2,0)
