Alex: Focusing on Graphs
In this lesson, students will solve systems of linear equations by graphing. Systems of linear equations are two or more linear equations together.
Illustrative Mathematics
Illustrative Mathematics: A Rei Pythagorean Triples
This task has two separate goals: the first is to solve a pair of equations, one quadratic and the other linear. The second goal is to observe that a point that lies on a circle gives rise to a Pythagorean triple. Aligns with A-REI.C.7.
