What is the slope of the line represented by the equation \(y = -2x + 4\)?

Solve the equation and check the solution. \( -35=\frac{5}{7} x \)

\( A = \left[ \begin{array} { r r r } { 3 } & { - 1 } & { - 1 } \\ { 1 } & { - 3 } & { 3 } \end{array} \right] , \quad x = \left[ \begin{array} { l } { x _ { 1 } } \\ { x _ { 2 } } \\ { x _ { 3 } } \end{array} \right] , \quad 0 = \left[ \begin{array} { l } { 0 } \\ { 0 } \end{array} \right] \)
