If y varies directly as x and y= 1 when x= 2. Find the value of k.
[tex] \\ y = kx \\ \\ [/tex]
Evaluate the values
[tex] \\ 1 = k(2) \\ \\ [/tex]
Divide 2 to both sides
[tex] \\ \frac{1}{2} = \frac{k(2)}{2} \\ \\ [/tex]
Cancel both 2 from the right side
[tex] \\ \frac{1}{2} = \frac{k( \cancel{2})}{ \cancel2} \\ \\ [/tex]
The value of k
[tex] \\ \large{\green{\boxed {\green {\sf{k = \frac{1}{2} }}}}} \\ \\ \\ \\ \\ [/tex]
