Unit 4 - Linear Equations

Algebra 1

Unit 4: Linear Equations

Approximately 35 days

By the end of this unit you should be able to say I CAN…

4.1 Find the slope of a line given a graph OR a set of points, OR  an equation (6 days)

4.2 Convert between slope-intercept and standard forms. (2 days)

4.3 Graph an equation from slope-intercept form.

4.4  Graph an equation from standard form using intercepts. ( 4.3&4.4 - 6 days)

4.5 Write an equation in slope-intercept form given a point and  slope, OR two points. (5 days)

4.6  Use linear equations to model real world applications and solve word problems. (6 days)

4.7  Find parallel or perpendicular equations given a slope and a point, or two points. (3 days)

4.8  Determine the correlation of a scatterplot and its correlation coefficient.

4.9  Use the rate of change and the line of best fit to  predict future outcomes. ( 4.8&4.9 - 4 days)

Unit Review and Exam - 3 days

Embedded within all modules  are the following learning targets

• Recognize units given or needed to solve problem
• Determine if the solution to a multi-step problem is reasonable using given units
• Choose appropriate units to represent a problem when using formulas or graphing.
• Interpret units or scales used in formulas or represented in graphs.
• Use units as a way to understand problems and to guide the solution of multi-step problems.
