Final Answer:

The line perpendicular to
\(g(x) = 2x - 8\)and passing through the point
\((6,3)\) is \(y = -(1)/(2)x + 6\).

Step-by-step explanation:

To find the line perpendicular to
\(g(x)\), we need to determine the negative reciprocal of the slope of
\(g(x)\). The given function
\(g(x) = 2x - 8\) has a slope of 2. The negative reciprocal of
2 is \(-(1)/(2)\). Therefore, the slope of the perpendicular line is
\(-(1)/(2)\).

Next, we use the point-slope form of a linear equation,
\(y - y₁ = m(x - x₁)\) where
\((x₁, y₁)\) is the given point. Plugging in \((6,3)\)
\((x₁, y₁)\) and
\(-(1)/(2)\) for \(m\), we get \(y - 3 = -(1)/(2)(x - 6)\).

Now, we simplify the equation to slope-intercept form
\(y = mx + b\), where \(m\) is the slope and \(b\) is the y-intercept. Distributing the
\(-(1)/(2)\) and rearranging terms, we get \(y = -(1)/(2)x + 6\).

In conclusion, the line perpendicular to
\(g(x) = 2x - 8\) and passing through the point
\((6,3)\) is represented by the equation
\(y = -(1)/(2)x + 6\). This line has a slope of
\(-(1)/(2)\), ensuring its perpendicularity to the original line, and it passes through the specified point
\((6,3)\).
