Visit his website here for more videos. Interpret solutions to linear equations and inequalities graphically. This is also known as the “slope.” The b represents the y-axis intercept. For distinguishing such a linear function from the other concept, the term affine function is often used. Sketching linear graphs using the y-intercept and the gradient with clear visual examples. A Review of Graphing Lines. The equation of a straight line can be written in many other ways. m = -2 and b = -1/3 m = -2 and b = -2/3. 5 = 2 x + 3. Practice: Plotting horizontal and vertical lines . Gradients Lines and equations You can see the effect of different values of m (the slope) and b (the y intercept) at Explore the Straight Line Graph . Solving Systems of Linear Equations: Graphing. Linear functions are typically written in the form f(x) = ax + b. How many solutions does this linear system have? 5b = -2b + 3. Matrices Trigonometry. The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run. There are three basic methods of graphing linear functions: In many business applications, two quantities are related linearly. This extensive set of printable worksheets for 8th grade and high school students includes exercises like graphing linear equation by completing the function table, graph the line using slope and y-intercept, graphing horizontal and vertical lines and more.
