#1/4#

Explanation:

For the perpendicular slope,

the product of both slopes are #-1#, this means that if the first slope is #m_1#, and the second slope is #m_2#, then #m_1⊥m_2# if and only if #m_1m_2=-1#.

Your first equation, #y=-4x+13#, so the slope is #-4#.

To find the perpendicular slope, plug #-4# for #m_1#.

#-4m_2=-1#

#m_2=1/4#

Thus, the perpendicular slope is #1/4#
