Solving Equations with Zero, One, or Infinitely Many Solutions

WebWhen two equations have the same slope, they will have either no solution or infinite solutions. By putting both equations into the form , we get: and. With the equations in this form, we can see that they have the same slope, but different y-intercepts. Therefore, there is no solution to this system. WebOne equation defines a plane. Two equations define two planes: and in geometry, two planes intersect in a line. Thus these two equations define a line, and you know this just because there are two of them. A third equation would define another plane, and the intersection of that plane and the line you have already got would give you a point. how much is ranger in tdsWebOct 17, 2024 · Exercise 8.1.1.
