In order to graph this function, we need to find at least two points that belong to the function.
Two good points to choose are the x-intercept (y = 0) and the y-intercept (x = 0).
So we have that:
So we have the points (-6, 0) and (0, -6).
Graphing these points and the line connecting then (this line will be our function), we have that:
