<prompt> Matrix mathbfM inachukua beginpmatrix 2 -1 endpmatrix hadi beginpmatrix 9 3 endpmatrix, na anza pmatrix 1 -3 mwishopmatrix hadi anzapmatrix 7 -1 endpmatrix. Tafuta picha ya mstari y 2x 1 chini ya mathbf M. Eleza jibu lako katika fomu y mx b.  <response>: Tunayo mathbfM anzapmatrix 2 -1 endpmatrix anzapmatrix 9 3 endpmatrix na mathbfM anza pmatrix 1 -3 mwishopmatrix anzapmatrix 7 -1 mwishopmatrix. Kisha mathbfM anzapmatrix 6 -3 mwisho pmatrix anzapmatrix 27 9 mwishopmatrix, hivyomathbfM anzapmatrix 6 -3 mwishopmatrix - mathbfM anzapmatrix 1 -3 mwishopmatrix anzapmatrix 27 9 mwishopmatrix - anzapmatrix 7 -1 mwishopmatrix.Hii inatupa mathbfM beginpmatrix 5 0 mwishopmatrix anzapmatrix 20 10 mwishopmatrix, hivyomathbfM anzapmatrix 1 0 mwishopmatrix anzapmatrix 4 2 mwishopmatrix.KishamathbfM anzapmatrix 1 0 mwishopmatrix - mathbfM anzapmatrix 1 -3 mwishopmatrix anzapmatrix 4 2 mwishopmatrix - anzapmatrix 7 -1 mwishopmatrix.Hii inatupa mathbfM beginpmatrix 0 3 endpmatrix anzapmatrix -3 3 mwishopmatrix, hivyomathbfM anzapmatrix 0 1 mwishopmatrix anzapmatrix -1 1 mwishopmatrix.Mwishowe,anzaalignmathbfM anzapmatrix 1 3 mwishopmatrix mathbfM anzapmatrix 1 0 mwishopmatrix 3 mathbfM anza pmatrix 0 1 mwishopmmatrix anzapmatrix 4 2 mwishopmatrix 3 anzapmatrix -1 1 mwishopmatrix anzapmatrix 1 5 mwishopmatrix.endalignTangu anzapmatrix 0 1 endpmatrix na beginpmatrix 1 3 endpmatrix ziko kwenye mstari y 2x 1 , tunataka kukokotoa mlinganyo wa mstari kupitia beginpmatrix -1 1 endpmatrix na beginpmatrix 1 5 endpmatrix. Mlinganyo wa mstari huu ni y 2x 3.
