Expressions and Equations
7.EE.B.4.B— Solve word problems leading to inequalities of the form px + q > r or px + q < r, where p, q, and r are specific rational numbers. Graph the solution set of the inequality and interpret it in the context of the problem.For example: As a salesperson, you are paid $50 per week plus $3 per sale. This week you want your pay to be at least $100. Write an inequality for the number of sales you need to make, and describe the solutions.

Expressions and Equations
8.EE.B.5— Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways.For example, compare a distance-time graph to a distance-time equation to determine which of two moving objects has greater speed.

Expressions and Equations
8.EE.B.6— Use similar triangles to explain why the slope m is the same between any two distinct points on a non-vertical line in the coordinate plane; derive the equation y = mx for a line through the origin and the equation y = mx + b for a line intercepting the vertical axis at b.

Unit 6 Write Linear Equations 6.1 Write Equations in Slope-Intercept Form 6.2 Use Equations in Slope-Intercept Form 6.3 Equations in Parallel/Perpendicular Form. Give examples of linear equations in one variable with one solution, infinitely many solutions, or no solutions. Show which of these possibilities is the case by successively transforming the given equation into simpler forms, until an equivalent equation of the form x = a, a = a, or a = b results (where a and b are different numbers). This unit is all about linear topics, which is a major focus of Common Core Algebra I. We develop general methods for solving linear equations using properties of equality and inverse operations. Thorough review is given to review of equation solving from Common Core 8th Grade Math.
