Question

On a piece of graph paper, graph the line x - y < 0.

Which of the three points below is within the graph of x - y < 0?

Answer 1

x - y < 0

-y < -x

 

Dividing by -1, the sign reverses.

 

y > x

 

Graph the line y = x with a dotted line, then plot each point to sit which is above that line.
