White an equation in the form \( y=m x+b \) of the line that is described. The line has the same \( y \) intercept as the line whose equation is \( 2 y=8-3 x \) and is paralled to the line whose equation is \( x+y=1 \). The equation of the line is \( y=\square \) (Simplity your answer. Use integers or fractions for any numbers in the expression.)

Вычислить следующие определители: а) \( \left|\begin{array}{cc}1 & -2 \\ -2 & 4\end{array}\right| \); б) \( \left|\begin{array}{ccc}1 & 2 & 0 \\ 0 & 0 & 3 \\ 5 & 0 & -1\end{array}\right| \), 2. Найти точку пересечения прямых \( l_{1}: 3 x-2 y=0 \) и \( l_{2}: y=-x+5 \). Построить прямые.
