I know how to find the line of regression when given the set of values of x and y. But in this question i don't have any idea what to do.
I am a beginner . I will really appreciate the help.

Given $b_{yx}=\dfrac{1}{7}$ and $b_{xy}=c$. On using the property of the regression coefficients \begin{eqnarray*} r^2 &=& b_{yx}\times b_{xy}\\ &=& \left(\dfrac{1}{7}\right)c\\ c &=& 7\cdot r^{2} \end{eqnarray*} As $r^2$ lies between 0 and 1, hence, $0\leq c \leq 7$.
