<reasoning>
Define intercepts on coordinate plane
Using the Coordinate Plane and Ordered Pairs knowledge points
- The \(x\)-intercept occurs where the line crosses the \(x\)-axis, meaning \(y = 0\). It is written as \((x, 0)\).
- The \(y\)-intercept occurs where the line crosses the \(y\)-axis, meaning \(x = 0\). It is written as \((0, y)\).
Calculate the x-intercept
Using the Linear Equations knowledge point
\[
\]
The \(x\)-intercept is \((16, 0)\).
Calculate the y-intercept
Using the Linear Equations knowledge point
\[
\]
The \(y\)-intercept is \((0, 8)\).
