Slope Intercept Form

Foldable

Slope Intercept Form y m x + b =

= + Inside the Flaps m is the slope b is the y intercept y is the dependent variable x is the independent variable b is the y intercept

m = 2, b=5 m = -1/2, b=-7 m = -6, b=13 m = 3/4, b= -5 m = -9/7, b=36 m = 3/2, b=-3007 m = 10, b=6 m = 17, b=22 m = 15, b=-12 m = -55, b=-101

Use the information to write an equation in slope intercept form. Slope = 4, y intercept = -6 Slope = −𝟐 𝟑 , y intercept = 5 Slope = 0, y intercept = -3 y = 4x - 6 y = -2/3x + 5 y = 0x – 3 y = -3
