According to ques,
Since, the line is passing through the point (1, 0), then
\[\left( 0\text{ }\text{ }1 \right)\text{ }\left( 1\text{ }+\text{ }1 \right)\text{ }=\text{ }c\left( 1 \right)\Rightarrow c\text{ }=\text{ }2\]
Thus, the required solution is \[\left( y\text{ }\text{ }1 \right)\text{ }\left( x\text{ }+\text{ }1 \right)\text{ }=\text{ }2x.\]
