Observations
The Observations help students start to uncover the types of solutions that arise in systems of
linear equations. If necessary, tell students how to find the
Observations section.
Students are asked to observe the number of solutions from the given graph. They should
question whether they are seeing enough of the graph to make a conjecture about the number of
solutions.
Students see the answer
after the third observation
question.
