see below

Use the formula $tan θ = \frac{y}{x}$ $tan theta =y/x$

$θ = {tan}^{- 1} (\frac{y}{x})$ $theta=tan^-1 (y/x)$

Therefore,

$θ = \frac{- 7 π}{4}$ $theta=(-7pi)/4$

${tan}^{- 1} (\frac{y}{x}) = \frac{- 7 π}{4}$ $tan^-1 (y/x)=(-7pi)/4$

$\frac{y}{x} = tan (\frac{- 7 π}{4})$ $y/x=tan((-7pi)/4)$

$\frac{y}{x} = 1$ $y/x = 1$

$:.y=x$
