Compare properties of two functions each represented in different ways 2. Spend less time in your class having students copying notes and more time in class letting them practice the materiallesson 1 relationslesson 2 defining functionslesson 3 finding domain an. The goal of solving a linear equation is to find the value of the variable that will make the statement equation true. Perform operations to both sides of the equation in order to isolate the variable. Mapping or transformation x is mapped or transformed to y by linear function y ax sample problems. Manipulate an expression in order to reveal and explain different properties. Make a table of values to find ordered pairs that satisfy the equation.

An equation is a statement that says two mathematical expressions are equal. Solving systems of linear equations by graphing hw. Graph transformationschanges equations a a b b a a b b. Regardless of where the point is located, the steepness of the line in.
Linear programming deals with the problem of optimizing a linear objective function subject to linear equality and inequality constraints on the decision variables. Such a function can be used to describe variables that change at a constant rate. Use 2, 0, 2 to start unless it is a real life problem. Leave any comments, questions, or suggestions below. Standard form any linear equation can be written in, ax by c, where a, b, and c are integers whose greatest common factor is 1. The standard form of a linear equation is ax by c, where a 0, a and b are not both zero. Choose values for x and find the corresponding values for y.
Writing a linear function using a graph use the graph to write a linear function that relates y to x. Write the inequality that is represented in the graph shown. Their comments and corrections have greatly improved the exposition. A linear function is a function whose graph is a straight line. These notes were prepared by joseph lee, a student in the class, in collaboration with prof. Students use notes to graph linear functions and then practice with the foldables provided. Linear programming has many practical applications in transportation, production planning. The goal of this text is to teach you to organize information about vector spaces in a way that makes problems involving linear functions of many variables easy.
David cherney, tom denton, rohit thomas and andrew waldron. This is the 5th lesson in unit 2 algebra 2 linear equations and functions. A linear equation in one variable is an equation which can be written in the form. Solving linear equations metropolitan community college. For example, the following table shows the accumulation of snow on the morning of a snowstorm. However, for the purposes of this lesson we are going to stick with an 2d,xy system. Explain to students that this investigation explores the use of functions to model the perimeter of a rectangle. Syllabus b2a explain the structure of linear functions and equations. One aspect of linear programming which is often forgotten is the fact that it is also a useful proof technique. It always helps to have a class roster when doing this so that you can make notes by individual student names. Linear functions and transformations notes functions 2 this is interesting because it allows us to describe everything we see in the world using an xy,z coordinate system.
Comparing linear, quadratic, and exponential functions notes 2 standards mgse912. For each of the linear functions on the graph below, compare it to the linear parent function in terms of vertical shifts and vertical compressions. Identify the parameter that determines the change and determine the function rule. A linear equation in one variable is an equation with the exponent 1 on the variable. Linear algebra is the study of vectors and linear functions. Constructing linear equations in slopeintercept form constructing linear equations in slopeintercept form from graphsslopeintercept form from table online practice identifying slope of a line line graph intuition graphing linear equations linear function intercepts print notes section 2. Sketch the following functions on the same set of axes, using the dual intercept method. Lakeland community college lorain county community college. All x values must have a common difference quadratic see same y more than once. Rate of change and slope rate of change shows relationship between changing quantities. It is also the building block for combinatorial optimization. On a graph, when we compare rise and run, we are talking about steepness of a line slope. In broad terms, vectors are things you can add and linear functions are functions of vectors that respect vector addition. Write an equation of the line that passes through the point 1,2 and has a slope of 3.
