The variation equation is xy = a^3
<h3>How to determine the equation?</h3>
An inverse variation is represented as:
xy = k
Where k is the constant of variation
When y = a and x =a^2, we have:
k = a * a^2
Evaluate
k = a^3
Substitute k = a^3 in xy = k
xy = a^3
Hence, the equation is xy = a^3

The total number of pieces of chalk in the classroom will be the number of pieces in the 4 boxes in addition to the six individual pieces.
The average box of chalk holds 12 pieces of chalk
This means that 4 boxes have 12*4 = 48 pieces
Total number of pieces = 48 + 6 = 54 pieces of chalk
Answer:
y=-3x+5
Step-by-step explanation:
y=mx+b
m=slope or gradient (=-3)
y=-3x+b
Add your points
(2, -1)
-1=(-3 x 2)+b
-1= -6+b
-1+6=b
b=5
y=-3x+5
