Solve the following system of linear equations by graphing. (−5. If the system has no solution, enter NO SOLUTION for each answer. If the system has infinitely many solutions, enter INFINITELY MANY for each answer.) y = 4x + 1 y = −4x − 7
You just graph each one separately and the answer is where they cross.
These 2 are both lines so if the gradients are the same they will be parallel and never cross If one equation is a multiple of the other eg 3x-2y=7 and 6x-4y=14 then they are the same line and there will be an infinite number of solutions. Otherwise there will be 1 solution where they cross.
