=Stage 1 - Identify Desired Results= Grade 8 Students understand and solve problems involving linear equations. ||
 * **Establish Goals (MLR):** **(G)** ||
 * Maine Learning Results: Mathematics- D, Algebra, Functions and Relations.

//What understandings are desired?//
• Linear relationships are characterized by a constant rate of change, k. • Lines can be used to symbolize real life situations, like acceleration. ||
 * **//Students will understand that://** **(U)** ||
 * • The graph of a linear relationship y=kx+b is a line. K being slope and b the y-intercept.

//What essential questions will be considered?//
• Why is a line characterized by it's slope? • How can linear equations be used in real life. ||
 * **Essential Questions:** **(Q)** ||
 * • How does changing the value of k and b effect the graph of the linear equation?

//What key knowledge and skills will students acquire as a result of this unit?//
and, distance formula. • Terminology: linear, equation, slope, y-intercept, x-intercept, graph. • Increasing k gives a steeper line, b moves the whole line, and equations can be applied to real life. || • represent a line with a linear equation. • derive a line from linear equations. • be aware that lines are characterized by slope. • argue why lines are charicterized by slope. • adapt linear equations to describe parts of their lives. • assume the role of a professional that uses linear equations in their work. ||
 * **//Students will know://** **(K)** || **//Students will be able to://** **(S)** ||
 * • y=kx+b, y=x line, piont slope formula,
