Question

Write an equation of the direct variation that includes the point (5,1)

Answer 1

y = 5x

Explanation:

X=5 and Y=1

Direct variation can be represented by the equation y=kx.

Therefore,

1 = k(5)

5 = k

Now you use, k = 5 to write the direct variation equation.

Which gives you the answer y = 5x

Answer 2

y = 1/5k

Explanation:

y = kx

1= k(5)

1/5 = l
