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. Graph the functions on a coordinate plane . You can use a graphing utility to find that the coordinates of the intersection points are approximately ( 4.36 , 0.64 ) and ( 5.76 , 0.76 ) . Linear functions have the form f (x) = m x + b, where the slope m and b are real numbers. To find the x-intercept, if one exists, set f (x) = 0 and solve for x. Since y = f (x) we can use y and f (x) interchangeably. Any point on the graph of a function can be expressed using function notation (x, f (x)). More Complicated Functions: Introduction to Linear Functions. Abstract. This lesson is designed to introduce students to the idea of functions composed of two operations, with specific attention to linear functions and their representations as rules and data tables, including the mathematical notions of independent and dependent variables. A linear equation is an equation with two variables whose graph is a line. The graph of the linear equation is a set of points in the coordinate plane that all are solutions to the equation. If all variables represent real numbers one can graph the equation by plotting enough points to recognize a pattern and then connect the points to include ... The coordinate plane As you remember from pre-algebra a coordinate plane is a two-dimensional number line where the vertical line is called the y-axis and the horizontal is called the x-axis.

If you are given an equation of a straight line and asked to draw its graph all you need to do is find two points whose coordinates satisfy the equation and plot the points. There are two commonly used methods to find two points. Using the y-intercept and one other point 4. TOOLS Place a pencil on a coordinate plane to represent a line. Move the pencil to represent different lines and evaluate each conjecture. a. True or false: A line can have more than one x-intercept. b. rue or false: If the end behavior of a line is that as x increases, y increases, then the function values are increasing over the entire domain. Polar equation of a curve. The equation defining an algebraic curve expressed in polar coordinates is known as a polar equation. In many cases, such an equation can simply be specified by defining r as a function of φ. The resulting curve then consists of points of the form (r(φ), φ) and can be regarded as the graph of the polar function r. If the relation is not a function the graph contains at least two points with the same x-coordinate but with different y-coordinates. The relation portrayed in the graph to the left shows a function whereas the relation in the graph to the right is not a function since the vertical line is crossing the graph in two points. Identify the growth/decay factor and initial value in problem situations, tables, graphs, and equations that represent exponential functions Determine whether an exponential function represents a growth (increasing) or decay (decreasing) pattern, from an equation, table, or graph that represents an exponential function Which equation represents the function graphed on the coordinate planes g(x)=[x+1]+3 - 12219421 We can easily determine whether or not an equation represents a function by performing the vertical line test on its graph. If any vertical line intersects the graph more than once, then the graph does not represent a function. If an algebraic equation defines a function, then we can use the notation f (x) = y. To graph the equation of a line, we plot at least two points whose coordinates satisfy the equation, and then connect the points with a line. We call these equations "linear" because the graph of these equations is a straight line. There are two important things that can help you graph an equation, slope and y-intercept. 7.3 GRAPHING FIRST-DEGREE EQUATIONS. In Section 7.1, we saw that a solution of an equation in two variables is an ordered pair. In Section 7.2, we saw that the components of an ordered pair are the coordinates of a point in a plane. Thus, to graph an equation in two variables, we graph the set of ordered pairs that are solutions to the equation.
