Y varies directly as X,Y=32 when X=4
y=kx
32=4k
k=8 huh?
To find the constant of variation (k) in the direct variation equation, you need to use the given values.
The direct variation equation is of the form: Y = kX
We are given that Y = 32 when X = 4.
Now substitute these values into the equation and solve for k.
32 = k * 4
To solve for k, divide both sides of the equation by 4:
32/4 = k
8 = k
Therefore, the constant of variation (k) is 8.
