Question

How do you solve the system by graphing 2x–y=4 and 4x–2y=−8?

Answer 1

first make graph of 2x-y=4 and on the same graph make graph of 4x-2y=-8 then see both the lines if the lines are parallel then it has no solution , is the lines are intersecting then you will get a point which will give you the coordinates of x and y and if the lines are coincident then it will have infinite solutions
