Two lines, a and b, are represented by the equations given below: line a: 2x + 2y = 8 line b: x + y = 4 which statement is true about the solution to the set of equations? it is (8, 4). it is (4, 8). there is no solution. there are infinitely many solutions. will give 100 points to the best answer.

Given: lines a and b are parallel and line c is a transversal. prove: 2 is supplementary to 8 what is the missing reason in the proof? statement reason 1. a || b, is a transv 1. given 2. ∠6 ≅ ∠2 2. ? 3. m∠6 = m∠2 3. def. of congruent 4. ∠6 is supp. to ∠8 4. def. of linear pair 5. ∠2 is supp. to ∠8 5. congruent supplements theorem corresponding angles theorem alternate interior angles theorem vertical angles theorem alternate exterior angles theorem
