Question

Graph the inequality on a plane. Shade a region below or above. Y < - 1

Answer 1

In order to graph the inequality on the coordinate plane, we first need to find it's border, which is delimited by the line below:

`y=-1`

This line is a straight line parallel to the x-axis and that passes through the y-axis at the point (0, -1). Since the original inequality has a "less" sign, we need to make this boundary line into dashes.

Now we can analyze the inequality:

`y<-1`

Since the signal is "<", we need to shade all the region of the coordinate plane for which y is below -1, this means that we have to paint the region below the line. The result is shown below:
