  graph y=-2 and 3x-y=-1



             and name if it has no solution, one solution, or infinitely many solutions if it has one solution name it





Graph y = -2

Graph 3x - y = -1

         We will use slope - intercept form y = mx + b, where m=slope

and b = y-intercept



         Rewrite the equation 3x - y = -1 to y = mx + b

                                   y = 3x + 1



m = 3 and b = 1, point is located (0,1)



first points is located (0,1). using the slope 3 or 3/1, we can locate the 

second point then draw a line passing through the two points. slope 3/1 means 

move 3 units upward and 1 unit to the right.



Here is the graph

GRaph them in one coordinate plane.

One solution (-1,-2). It is where the two graph intersect.
