An equation with two unknown values will have infinitely many solutions. or \(x=100\), \(y=-90\), etc. But you can use two equations together, if they have the same two unknowns, to make one ...

Follow these steps to draw a parabola with the given equation: y = 2 2 − 4x + 1 In this case, a is 2, b is -4 and c is 1. The parabola's vertex is (h,k). This is about to get really confusing ...
