This is a ten by ten graph on my graphing calculator. Hope it helps.
Explanation: y=mx+b; -6 is b, or the y intercept. This means the line will cross the y axis at the point (0,-6). The slope(m) is 1/4, which means you would move up one from (0,-6) and four to the right (do the opposite to go down/left; down one, left four).
