Unit 2 linear functions homework 5 solving systems of equations by elimination and applications

Linear Functions and Systems (Algebra 2 Curriculum - Unit 2) | All Things Algebra®

DISTANCE LEARNING UPDATE: This unit now contains a Google document with:

(1) Links to instructional videos. Videos are created by fellow teachers for their students using the guided notes from the unit.  Please watch through first before sharing with your students. They might not always be perfect but we are trying our best to help out where we can in a very limited time.

(2) A link to a Google Slides version of the unit. Each page is set to the background in Google Slides. There are no text boxes;  this is the PDF in Google Slides.  We are unable to do text boxes at this time but hope this saves you a step if you wish to use it in Slides instead! 

-------------------------------------------------------------------------------------------------------------------------

This bundle includes notes, homework assignments, two quizzes, a study guide and a unit test that cover the following topics:

• Domain and Range of a Relation

• Relations vs. Functions

• Evaluating Functions

• Linear Equations: Standard Form vs. Slope-Intercept Form

• Graphing by Slope-Intercept Form

• Graphing by x- and y-intercepts

• Vertical and Horizontal Lines

• Parallel vs. Perpendicular Lines

• Writing Linear Equations: Given Point and Slope or Two Points

• Linear Equation Applications

• Linear Regression

• Solving Systems of Equations by Graphing, Substitution, and Elimination

• Systems of Equations Applications

• Solving Systems with Three Variables

• Graphing Linear Inequalities

• Graphing Systems of Linear Inequalities

NEW: Assessments are now EDITABLE! Now you can easily make multiple versions or customize to fit your needs! PowerPoint and Equation Editor (usually built in to PowerPoint) are required to edit these files. There is a folder titled "Editable Assessments" when you download. This is where you will find editable versions of each quiz and the unit test. If your Equation Editor is incompatible with mine, simply delete my equation and insert your own.

Standards

8.EE.C.8

Analyze and solve pairs of simultaneous linear equations.

8.EE.C.8a

Understand that solutions to a system of two linear equations in two variables correspond to points of intersection of their graphs, because points of intersection satisfy both equations simultaneously.

8.EE.C.8b

Solve systems of two linear equations in two variables algebraically, and estimate solutions by graphing the equations. Solve simple cases by inspection. For example, 3x + 2y = 5 and 3x + 2y = 6 have no solution because 3x + 2y cannot simultaneously be 5 and 6.

8.EE.C.8c

Solve real-world and mathematical problems leading to two linear equations in two variables. For example, given coordinates for two pairs of points, determine whether the line through the first pair of points intersects the line through the second pair.

MP1

Make sense of problems and persevere in solving them.

MP2

Reason abstractly and quantitatively.

MP4

Model with mathematics.

Each day, students complete a warm-up that usually consists of spiraling the previous day's material, in addition to older material.  Today's Warm-up problems (WU61) also extend the goals of yesterday's lesson.

A quick note - today's BRONZE problems are from Coach New York Grade 8.
