Pick a point on the line, drop a perpendicular to make a triangle, and then
using trig (and little intuition) find the required angle.

h(x) = csc(x) = 1/sin(x), so find where sin(x) is undefined (but not
infinite) and where sin(x) = 0; these points will be where csc(x) is
undefined.

Solve the given line into slope-intercept form itself (y = mx + b). The
slope of the perpendicular to this line will be the negative reciprocal of
the slope of the line. Now you have a point and a slope, so you should be
able to write an equation for the line.
The previous reply is right, this isn't calculus stuff unless you're
reviewing the prerequisites from precalc still... And if you're in calculus,
you should be able to do this stuff already.
