**Equation:**

23) \( y = \frac{1}{3} \csc \left( \frac{4}{5}x + \frac{\pi}{2} \right) \)

**Graph Details:**

The graph is a coordinate plane labeled with the \(x\)-axis and \(y\)-axis. There are tick marks on both axes to indicate scale, though no specific units or numbers are provided. The graph appears to be prepared for plotting the function given by the equation above. 

**Function Description:**

This function involves the cosecant trigonometric function \(\csc\), which is the reciprocal of the sine function. The equation shows a transformation including a vertical scaling by \(\frac{1}{3}\) and a phase shift in the angle of the \(\csc\) function by \(\frac{\pi}{2}\). Additionally, the variable \(x\) is scaled by a factor of \(\frac{4}{5}\), affecting the period of the function.

**Graph Interpretation:**

The graph grid includes indicator dots for plotting ease. This setup will be useful for analyzing key points and asymptotes integral to graphing a \(\csc\) function, such as where the sine function would be zero (resulting in vertical asymptotes for \(\csc\)).

This equation may be used to practice graph transformations involving trigonometric functions. Understanding these concepts is crucial in precalculus and calculus studies.
