\[\textbf{а)}\ y = kx + b;\ \ A(0;1);B( - 2;0)\]

\[1 = 0k + b\]

\[b = 1.\]

\[0 = - 2k + 1\]

\[2k = 1\]

\[k = 0,5.\]

\[y = 0,5x + 1\]

\[y - 0,5x = 1.\]

\[\textbf{б)}\ y = kx + b;\ \ A( - 2;0);\ \ \]

\[B(0; - 1)\]

\[- 1 = 0k + b\]

\[b = - 1.\]

\[0 = - 2k - 1\]

\[- 2k = 1\]

\[k = - 0,5.\]

\[y = - 0,5x - 1\]

\[y + 0,5x = - 1.\]

\[\textbf{в)}\ y = - 1.\]
