write the equation of a line that is perpendicular to y=−1 and that passes through the point (8,-4)

1. what are the missing reasons in the proof 2. it's in the second picture and 3

(01.02 lc) angle abc has point e on ray ba and point d on ray bc. points e and d are equidistant from point b. to bisect angle abc, which of the following needs to be identified for the construction? the distance between points e and d the point in the angle that is equidistant from points e and d the endpoint of rays ba and bc the point outside of the angle that is equidistant from points e and d

Need on this geometry question. explain how you did it.
