ADV/INT ALG ONE LESSON 3. 1 = Graphing Linear Equations = REAL WORLD: Many situations in nature are BIVARIATE; and, thus, can be expressed as linear equations and graphed onto a coordinate plane. ~ Money: the # of sodas you buy (x) costs this much (y) ~ Weight: the # of weights you add to a bar (x) totals this much (y) ~ Sports: if average (x) strikeouts a game, your season total is this (y) ~ Science: this many tons of coal (x) produces this much power (y)

ADV/INT ALG ONE LESSON 3. 1 = Graphing Linear Equations = MATH WORLD Unit One = we learned about one-variable EQ/INEQ Unit Two = focus on LINEAR EQ/IN. . . How to use/know them… This is one of the foundations of algebra – the linear equation. You must be able to go back and forth between the following: observation table ordered pairs graph equation Linear functions are the foundation for the rest of ALG I and ALG II.

ADV/INT ALG ONE LESSON 3. 1 = Graphing Linear Equations = TERMS X = input, independent variable, domain, horizontal axis, etc. Y = output, dependent variable, range, vertical axis, etc. Bivariate data = data having 2 variables (ordered pair of x, y) Coordinate Plane. . . Intersecting x and y axes forming 4 quadrants Linear Equation = an equation having an x, a y, or both – to 1 st power Standard Form of a Linear Equation. . . Ax + By = C Relation = x and y together. . . Function = each x ONLY has one y

ADV/INT ALG ONE LESSON 3. 1 = Graphing Linear Equations Let’s work some examples. . . Mr. Miller = # 1 and # 2 Alone = your card # (Ace = 1, Face = 10, Joker = choice) Partner = share Pod = share HW = finish Skills Practice ODD

ADV/INT ALG ONE LESSON 3. 1 = Graphing Linear Equations Day One: Notes, Examples, CW/HW = Skills Practice ODD TOTD: Half-page of paper, one sentence and linear equation for you and friends going to a movie. $ 5 per ticket and $ 10 to park your one car you all rode in. Day Two: Board Work, CW/HW = Practice ODD
