Can someone explain how to do this problem?

For x= -1, find -1 on the x axis and draw a vertical line. For y=6, look for 6 on the y axis and draw a horizontal line.

You have to put the two numbers on the graph where they have to go. The six goes on the y axis(it's the line going up and Down) and you put the -1 on the x axis (which is the horizontal line, going left to right)

Hope this helps
