Answer:
-2/5
Step-by-step explanation:
First, let's find the slope of line s using slope formula:
[tex]m_s = \frac{8-3}{5-3} = \frac{5}{2}[/tex]
The slope of a line perpendicular to any is the negative reciprocal of the slope of that line. So, since line s has a slope of 5/2, slope of line t is:
[tex]m_t = -\frac{2}{5}[/tex]
