How would I solve this question? y = -1 1/8 - 7/8x -4x + 9y = -22 x = ?, y = ?

Having a hard time understanding this question (see attachment).

What is the slope of any line parallel to the line 8x+9y=3 in the standard (x,y) coordinate plane?

Nina has prepared the following two-column proof below. she is given that ∠oln ≅ ∠lno and she is trying to prove that ol ≅ on. triangle oln, where angle oln is congruent to angle lno nina made two errors in the proof. identify and correct the errors.
