what is the equation, in point-slope form of the line that is
perpendicular to the given line and passes through the
point (-4,-3)?
o
y + 3 = -4(x + 4)
y+3= - (x + 4)
y + 3 = 4(x + 4)

y + 3 = 4(x + 4)

There is not a given equation, so it is impossible to answer this question. I apologise.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
