Graphing linear equations

In the case that you have created two equations that can be graphed that are not either the same line or parallel lines, then at some point on the graph, there will be the overlap, or the vertex. But assuming that a point that you choose only satisfies one of the equations, it will be a point on a single line that cannot be on the vertex.
To find the slope follow this equation....Y2-Y1= X2-X1= the y intercept will be in the numerator and the x intercept will be in the denominator. When trying to determine the slope of the X and Y intercepts....you need to realize that you are trying to find the DIFFERENCE between y1 and y2.....and x1 and x2.... The difference by definition in mathamatical terms is subtraction.
