What is the equation of the graph below? y=sec(x)-4

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte

Ofin . (2,4) (2,1) a. y= 2 b. x= 2 c. x= -2 d. y= 2x
