Curriculum Outcome (C4) To determine the equations of lines by obtaining their slopes and y-intercepts from graphs, and sketch graphs of equations using y-intercepts and slopes TOC D.May - Graphing: Slope y-Intercept Form
Slope y-Intercept Form TOC D.May - Graphing: Slope y-Intercept Form
Finding the Slope http://www.freegraphics.com/clipart/Alphabets/Irradescent/free-clipart1.shtml The rise is the change in the y values (how many jumps up or down). The run is the change in the x values (how many jumps left or right). Formula Slope =Rise Run = 2 1 = 2 Graph by; Matt VanRaalte TOC D.May - Graphing: Slope y-Intercept Form
Finding the y-Intercept http://www.freegraphics.com/clipart/Alphabets/Irradescent/free-clipart1.shtml The y-intercept (b) is where the line crosses the y-axis and x = 0. In this example: b = 1 y-intercept TOC Graph by; Matt VanRaalte D.May - Graphing: Slope y-Intercept Form
