2x=18y
divide 2
x=9y
9y=x
divide by 9
y=1/9x
k=1/9
In order to find the<u> roots</u> of the cubic equations by <u>graphing</u> you have to follow those steps
we have

we know that
The <u>roots</u> of the function are the values of x when the value of the function is equal to zero
Using a <u>graphing </u>tool
see the attached figure
The<u> roots</u> are

therefore
