The table shows numbers of books read by students in an english class over a summer and the students’ grades for the following semester. a) find the line of best fit. write in the equation for the line of best fit. b) use your equation to predict the grade of a student who reads 15 books. show all your work.

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
