Graph the linear inequality on the canvas below by hand, without the aid of a graphing utility.
After that, graph the inequality on the embedded Desmos graphing calculator above.
Edit your graph, as needed.
As always, include important graph detail: label the axes, indicate axis scale by labeling at least one value on each axis, add arrows to the ends of lines, ensure that your line is appropriately dashed or solid, and shade one side of the boundary line, as appropriate.

Writing: To graph the inequality below, do you shade above or below the boundary line? Explain.

Below; The inequality sign < indicates all values less than. y-values decrease as you move down a coordinate plane.
Above; The inequality sign < indicates all values less than. y-values decrease as you move down a coordinate plane.
