How do you graph y<-3?
The graph of y< -3 is all points where the y-coordinate is less than -3. The x-coordinate can be anything.
So to graph y< -3, you draw the line y = -3 and all points lying below the line are part of the graph required graph. As points where y is equal to -3 are not to be graphed, we do not consider points on the line y = -3, only those that lie below the line.
The graph of y< -3 is all points that lie below the line y = -3.
You draw a line going through the 3 on the y intercept and shade everything below it
