y = -2x + 5
3. Solution Interpretation
What does it mean when I ask “What is the solution to this linear equation?”? What does a solution normally look like (the format/notation)?
4. Substitution Review
Solve the following system of equations (answer in a coordinate point (x , y) ):
y = 1
x + y = 9
5. SAT-Style Systems Application
