Learning Goals This week, students will solve systems of equations via graphing and substitution, as well as explore using linear combinations to solve a system of linear equations. Analyze a system of linear equations to determine if it has one solution, no solution, or infinitely many solutions. (A-REI.6)
In this item, students must recognize that when given a system of two equations in two variables, replacing one equation by the sum of that equation and a multiple of the other produces a system with the same solutions. Answer choice A is incorrect because only the coefficient for y has been multiplied by -1 in the second equation.
