The answer of my classmate that the line has a positive slope is CORRECT. This is because the line is most likely to lean to the right. The slope can be calculated through the equation,
slope = rise / run = change in y / change in x
If both are negative, the slope is POSITIVE.
Answer: The first graph.
This can be found by looking at the y-intercept and plugging in values for x.
We know that
tan²(A)+1 = sec²(A)--------> tan²(A)= sec²(A)-1
tan²(A)= (4/3)²-1------> tan²(A)=16/9-1-----> 7/9
tan²(A)=7/9
if the angle A is in the IV quadrant
then
tan (A) is negative
therefore
tan (A)=-√(7/9)-----> tan (A)=-√7/3
so
cot (A)=1/tan(A)------> cot (A)=-3/√7----> -(3/7)*√7
the answers are
a) the identity is tan²(A)= sec²(A)-1
b) tan (A)=-√7/3
