Solve the following python programming problem given the following code:
# Define a Linear class
class Linear(keras.layers.Layer):
    def __init__(self, units=32, input_dim=32):
        super(Linear, self).__init__()
        w_init = tf.random_normal_initializer()
        self.w = tf.Variable(
            initial_value=w_init(shape=(input_dim, units), dtype="float32"),
            trainable=True,
        )
        b_init = tf.zeros_initializer()
        self.b = tf.Variable(
            initial_value=b_init(shape=(units,), dtype="float32"), trainable=True
        )

    def call(self, inputs):
        return tf.matmul(inputs, self.w) + self.b

Given the above code, generate some markdown instructions for it.

The Layer class: the combination of state (weights) and some computation
One of the central abstraction in Keras is the Layer class. A layer
encapsulates both a state (the layer's "weights") and a transformation from
inputs to outputs (a "call", the layer's forward pass).
Here's a densely-connected layer. It has a state: the variables w and b.
