Determine two angles between 0° and 360° that have a secant of -3 (show work) thank you so much

Two rigid transformations are used to map abc to qrs. the first is a translation of vertex b to vertex r. what is the second transformation? a reflection across the line containing ab a rotation about point b a reflection across the line containing cb a rotation about point c

The lines shown below are parallel. if the green line has a slope of -1, what is the slope of the red line?

Any is very appreciated! (picture is provided below)not sure how to do this at all won't lie
