In the second quadrant, both cos and tan are negative while only sin is positive.
To find tan, we will use the following property below:

Sec is the reciprocal of cos. If cos is a/b then sec is b/a. Since cos is 2/3 then sec is 3/2

Since tan is negative in the second quadrant. Hence,

Answer
I think b= -4.75 in this equation
(-2,4) and (-4, - 8)
slope = (4 + 8)/(-2+4) = 12/2 = 6
answers are E and B
y - 4 = 6(x + 2)
y + 8 = 6(x + 4)
