Topic C combines learning from topics A and B to explore and model with systems of equations and inequalities.

Unit 4 Linear Equations Homework 10 Key

Identify solutions to systems of equations with three variables. — Relate the domain of a function to its graph and, where applicable, to the quantitative relationship it describes. Example Rewrite the equation 4x 2y 12 in slope-intercept form* 4x 2y 12 -4x 1. With just one of you and twenty of them, that's not so easy. Solve a system of linear equations graphically. PTASK, Who Has the Best Job? Construct a viable argument to justify a solution method. Modeling is best interpreted not as a collection of isolated topics but in relation to other standards. Possibly the most frustrating word for any math teacher - or parent - to hear. Determine if a function is linear based on the rate of change of points in the function presented graphically and in a table of values.

Internalization of Trajectory of Unit. — Write a function that describes a relationship between two quantities. Identify inverse functions graphically and from a table of values in contextual and non-contextual situations. — Understand that a function is a rule that assigns to each input exactly one output. — 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. — Interpret the equation y = mx + b as defining a linear function, whose graph is a straight line; give examples of functions that are not linear. Topic B expands students' understanding of a single-variable inequality to linear inequalities. Students will determine whether linear inequalities have a shaded region above or below a line. Write systems of inequalities from graphs and word problems. — Explain why the x-coordinates of the points where the graphs of the equations y = f(x) and y = g(x) intersect are the solutions of the equation f(x) = g(x); find the solutions approximately, e. g., using technology to graph the functions, make tables of values, or find successive approximations. Post-Unit Assessment Answer Key. — Explain each step in solving a simple equation as following from the equality of numbers asserted at the previous step, starting from the assumption that the original equation has a solution.
