A sum of scalar multiples of two or more vectors (such as c 1 Bold u plus c 2 Bold v plus c 3 Bold wc1u+c2v+c3w, where c Subscript ici are scalars) is called a linear combination of the vectors. Let iequals=left angle 1 comma 0 right angle1,0 and jequals=left angle 0 comma 1 right angle0,1. Express left angle negative 4 comma 9 right angle−4,9 as a linear combination of i and j (that is, find scalars c 1c1 and c 2c2 such that left angle negative 4 comma 9 right angle−4,9equals=c 1c1iplus+c 2c2j).
