      y=3x-6


      You can give x a value and make points. Then graph  the points and draw a line.


             x             y       


            1             y = 3(1) - 6 = -3  >  (1, -3)


            2             y = 3(2) - 6 = 0    >  (2, 0)


            3             y = 3(3) - 6 = 3    >  (3, 3)


      Or, you can graph the equation as it is written. The slope is: m = 3 and the y-intercept is: b = -6.


      Do the y-intercept first (-6). On the y-axis, go down to -6. Then do the slope (3). Go up 3 and  one place to the right (x). From that point, go up 3 and to the right one. Repeat the cycle at least 3 times, up 3 and to the right one, then draw a line.


      Either way, you'll come out with the same graph.
