First let's determine the slope of the straight line

A perpendicular line fulfills the following relationship


m1m2=-1

Where

m1 = slope of the first straight line

m2 = slope of the perpendicular straight line


\begin{gathered} 4m2=-1 \\ m2=-(1)/(4) \end{gathered}

Now we are going to calculate the intersection point


\begin{gathered} b=y-mx \\ b=-4-(-(1)/(4))\cdot(-4) \\ b=-4-1 \\ b=-5 \end{gathered}

The equation of the line that passes through the point (-4,-4) with a slope of -1/4


y=-(1)/(4)x-5
