2. Even better… write it as y = 3x – 6
y = mx + b
slope
y-intercept
y = mx + b
y = 3x + (-6)
Even better… write it as
y = 3x – 6

3. 11  Plug in values for variables Distribute
slope
Point on the line
 Plug in values for variables
Distribute
Add or Subtract to get y alone 11

5. H = Horizontal V = Vertical
O = Slope is 0 U = Slope is Undefined
Y = Equation is y = # X = Equation is x = #
A Horizontal line has only a y-intercept.
The # in the equation IS the y-intercept
A Vertical line has only an x-intercept.
The # in the equation IS the x-intercept
