Explain why the $x$-coordinates of the points where the graphs of the equations $y = f(x)$ and $y = g(x)$ intersect are the solutions of the equation $f(x) = g(x)$ find the solutions approximately, e.g., using technology to graph the functions, make tables of values, or find successive approximations. Understand that the graph of an equation in two variables is the set of all its solutions plotted in the coordinate plane, often forming a curve (which could be a line).Ī-REI.D.11. Represent and solve equations and inequalities graphically.Ī-REI.D.10. Find the inverse of a matrix if it exists and use it to solve systems of linear equations (using technology for matrices of dimension $3 \times 3$ or greater).Ī-REI.D. Represent a system of linear equations as a single matrix equation in a vector variable.Ī-REI.C.9. For example, find the points of intersection between the line $y = -3x$ and the circle $x^2 + y^2 = 3$.Ī-REI.C.8. Solve a simple system consisting of a linear equation and a quadratic equation in two variables algebraically and graphically. Solve systems of linear equations exactly and approximately (e.g., with graphs), focusing on pairs of linear equations in two variables.Ī-REI.C.7. Prove that, 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.Ī-REI.C.6. Recognize when the quadratic formula gives complex solutions and write them as $a \pm bi$ for real numbers $a$ and $b$.Ī-REI.C.5. Solve quadratic equations by inspection (e.g., for $x^2 = 49$), taking square roots, completing the square, the quadratic formula and factoring, as appropriate to the initial form of the equation. Derive the quadratic formula from this form.Ī-REI.B.4.b. Use the method of completing the square to transform any quadratic equation in $x$ into an equation of the form $(x - p)^2 = q$ that has the same solutions.
