(x, y)
Linear Equations are set up like y=mx+b. What does the "m" represent?
The "m" represents the slope or the rate of change from one point to the next.

True or False: The all of the following formulas count as examples of direct variation
y= 2x
y= x/5
y= x2
y= 1/3x
False. y= x2 is not a direct variation, it's slope changes from each input to the next
