Answer:
-1/4
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(2-4)/(3-(-5))
m=-2/(3+5)
m=-2/8
simplify
m=-1/4
I believe the answer is cos^2 theta. Sec^2 theta on the right side of the equation is the inverse of Cos^2 theta, so multiplying the two together will get you 1. Cos^2 theta * Tan^2 theta = Sin^2 theta, and Cos^2 theta * 1 = Cos^2 theta. This all leads to the third and last step in the picture above.
