Lesson Plan: Lesson plans were written by Maryland mathematics educators and could be used when teaching the concepts.
 Goal 1 Functions and Algebra Expectation 1.2 The student will model and interpret real-world situations using the language of mathematics and appropriate technology. Indicator 1.2.3 The student will solve and describe using numbers, symbols, and/or graphs if and where two straight lines intersect.

### Lesson Plan

Systems of Linear Equations - Slope-Intercept Form
Objectives:
• Students will use the calculator to represent a situation as a table, graph, and equation.
• Students will write systems of equations and find solutions to systems of equations.
• Students will explain how they determined their solutions to a system of equations. Students will also justify their solutions.

### Lesson Plan

Systems of Linear Equations - Standard Form
Objectives:
• Students will write systems of equations and find solutions to systems of equations.
• Students will explain how they determined their solutions to a system of equations. Students will also justify their solutions.
• Students will write equations in standard form and then graph the equations using slope-intercept form.
