Work Step by Step

Given \begin{equation} y=4 x-22. \end{equation} This is a linear function with no restriction on the domain. The domain is all real numbers. The intercepts are \begin{equation} \begin{aligned} x&=0\implies y= -22 \\ y&= 0\implies x= \frac{22}{4}= 5.5. \end{aligned} \end{equation} The graph of the function is shown in the figure below with both intercepts labelled.
