I have many linear equations contained in a dataframe and I want to plot these equations in Python, the equations are in this format, for example:

enter image description here

How do I do this automatically?

b = row['b']
λ1 = row['λ1']
λ2 = row['λ2']
restricao = row['Restrições']

if restricao == '<=':
    # Se λ1 for zero
    if λ1 == 0:
        plt.plot([0, 0], [0, b / λ2], linestyle='solid')

    # Se λ2 for zero
    elif λ2 == 0:
        plt.plot([b / λ1, 0], [0, 0], linestyle='solid')

    # Se λ2 for zero
    elif b == 0:
        plt.plot([0, 0], [0, 0], linestyle='solid')

    # Se ambos λ1 e λ2 são diferentes de zero
    else:
        plt.plot([b / λ1, 0], [0, b / λ2], linestyle='solid')

elif restricao == '>=':
    # Se λ1 for zero
    if λ1 == 0:
        plt.plot([0, 0], [0, b / λ2], linestyle='solid')

    # Se λ2 for zero
    elif λ2 == 0:
        plt.plot([b / λ1, 0], [0, 0], linestyle='solid')

    # Se λ2 for zero
    elif b == 0:
        plt.plot([0, 0], [0, 0], linestyle='solid')

    # Se ambos λ1 e λ2 são diferentes de zero
    else:
        plt.plot([b / λ1, 0], [0, b / λ2], linestyle='solid')
