Re: Teach David

But of course we could just go Plot[4x+2,{x,1,6}] and get the graph immediately but do you want to see how m could do it exactly like you?

Re: Teach David

ans = Table[{x, 4 x + 2}, {x, 1, 6}];
Column[ans]

ListLinePlot[ans]

See you in a couple of minutes.

Re: Teach David

Bobbym, could we learn from the basics? Like how to calculate distance between two points?

Okay, do you have gebra, it will make these concepts easier to visualize?
