Question

two lines, r and m, are represented by the following equations: line r: 2x 2y = 18 line m: x y = 9 which statement is true about the solution to the set of equations? it is (18, 9). it is (9, 18). there are infinitely many solutions. there is no solution.

Answer 1

Line r is twice line m. i.e. r = 2s which means that they are linearly dependent.

Therefore there are infinitely many solution to the given set of equations.
