------------------------------------------------------------------
perpendicular to the line that contains(5/4,-2) and (3/4,-3)
-------------------------------------------------------------------

Those two points, slope %28-3-%28-2%29%29%2F%283%2F4-5%2F4%29=-1%2F%28-2%2F4%29=1%2F%281%2F2%29=2

Slope needed for a perpendicular line will be -1%2F2.


----------------------------------------------------
equation of the line that contains the point(2,-4)
----------------------------------------------------

You can start with point-slope form equation.
y-%28-4%29=-%281%2F2%29%28x-2%29
and simplify and adjust to slope-intercept form.
y%2B4=-x%2F2%2B1
y=-x%2F2%2B1-4
highlight%28y=-x%2F2-3%29
