Math Review of Linear Equations and Slope 150 150 Deborah

Math Review of Linear Equations and Slope

Overview Linear equations can be graphed by using intercepts or by changing the equation to standard form to make it easier to graph.  Horizontal and vertical lines have special relationships in terms of the standard form.  The slope of a line is a ratio that describes the steepness and direction of the line. Graphing by…
