We know that
in the IV quadrant
cos theta is positive
and
sin theta is negative
so
cot theta=cos theta/sin theta--------> cot theta must be negative
sec theta=1/cos theta------> sec theta must be positive
therefore
the answer is the option
<span>A. cannot be true because sec(theta) is greater than zero in quadrant 4</span>

Answer:
y = 1/3x + 5
Step-by-step explanation:
Step-by-step explanation:
y - y1 = m(x - x1)
y - (4) = 1/3(x - (-3)
y - 4 = 1/3(x + 3)
y - 4 = 1/3x + 1
y = 1/3x + 1 + 4
y = 1/3x +5
