NUR601 Before we begin graphing systems  of equations, a good starting point is to review NUR601 Before we begin graphing systems  of equations, a good starting point is to review our knowledge of 2-D graphs. These graphs are known as 2-D because they have two axes. Find an online image of a graph to use as the foundation of your discussion. (This is easily accomplished by searching within Google Images.)Using your graph as the example:1 Select any two points on the graph and apply the slope formula, interpreting the result as a rate of change (units of measurement required); and2 Use rate of change (slope) to explain why your graph is linear (constant slope) or not linear (changing slopes).Understanding 2-D GraphsLet's start by understanding the basics of a 2-D graph. A 2-D graph is a visual representation of a mathematical function or a set of data on two axes: the x-axis (horizontal) and the y-axis (vertical).Here is an example of a 2-D graph:Calculating Slope1.Selecting Two Points and Calculating SlopeLet's select two points on the graph. For instance, we can choose po
