Slope of a Line

Example

Graph the line whose y-intercept is –2 and whose slope is 7 3 .



Solution

Since the desired line has –2 as y-intercept, the line passes through the point (0,2). From this point, locate a second point using the given slope of the line, which is 7 3 . Follow the steps in the preceding example. The graph is shown in the figure below.
