    http://prntscr.com/7g5c3h here draw points on the graph you can draw triangle now you need h and b so find distance between (0,0)(0,3) AND (0,0)(4,0)

    formula to find distance is \[\huge\rm \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2}\]

    you DON'T have to use that formula just look at the graph and count how many unit its increasing vertical and horizontal

    Ok Thanks for the graph. I get it now. Wasn't sure what to do with vertices. I have an online class but have never had Geometry yet.
