Yes, Sam, where m is your slope and b is your y-intercept. Remember that slope equals rise/run or difference in y's/difference in x's.
So, you are going to start at (0,-6). How can 4 be rise/run? Wait, 4 = 4/1, right?
So, we go up 4 and right 1 to (1,-2). We can do the same from there to (2,2).
Remember also that 4 = -4/-1 also, so we can go from our y-intercept down 4 and left 1 to (-1,-10), etc.
The other way to graph is to pick different values for x. Try 1. 4(1)-6 = -2, so one point is (1,-2). Keep picking different x values, plot them and connect.
