Katen [24]

Answer:

\large\boxed{y=-2x+14}

Step-by-step explanation:

\text{Let}\ k:y=_1x+b_1\ \text{and}\ l:y=m_2x+b_2.\\\\l\ \perp\ k\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_1}\\============================\\\\\text{We have}\ y=\dfrac{1}{2}x+8\to m_1=\dfrac{1}{2}.\\\\\text{Therefore}\ m_2=-\dfrac{1}{\frac{1}{2}}=-2.\\\\\text{The equation of the searched line:}\ y=-2x+b.\\\\\text{The line passes through }(4,\ 6).

\text{Put thecoordinates of the point to the equation.}\ x=4,\ y=6:

6=-2(4)+b\\\\6=-8+b\qquad\text{add 8 to both sides}\\\\b=14
