(-3,2) (5,2) write in slope intercept form if someone could teach me how to find the y-intercept that would be great thank you!!

In the following diagram it is given that dec,ab || dc, ad || eb, and ad is congruent to bc. a)why isn't abc a parallelogram even though it has a pair of parallel sides and a pair of congruent sides b)explain why be must be congruent to bc. further explain what type of triangle this makes triangle abc and what it tells you about angle 1 and angle 2c) finally why must angle 3 be congruent to angle 1? further, explain why we know that angle 3 is congruent to angle 2

Me complete this proof! prove that a quadrilateral is a square. me with the steps for this proof.
