line graph XY axis cant do

I am teaching basic mathematics to a group of students and want to show them make a line graph in excel 2003. They have access to excel 2003 so I am wanting to use this.


I would input the data and graph X VS Y on a Cartesian plane.

i plot numbers i have on a excel sheet.
These numbers are say from -10 <x <10 for y=2x +1. i just need to see how the numbers look on a graph like a simple junior high mathematics problems.

So i just need the graph as i can already work out the points
