1. Definitions of Slope Slope is the rate of change of a linear equation.
Slope is the direction and steepness of a line.
Slope is rise over run. 𝐫𝐢𝐬𝐞 𝐫𝐮𝐧
Slope is the change in y over the change in x. 𝚫𝒚 𝚫𝒙 = 𝒚𝟐−𝒚𝟏 𝒙𝟐−𝒙𝟏

2. Slope-Intercept Form
𝒚=𝒎𝒙+𝒃 where m is the slope of the line and b is the y-intercept (0,b)

3. 3 rules: Ax + By = C “A” must be positive No fractions or decimals
Standard Form
3 rules: Ax + By = C “A” must be positive No fractions or decimals

4. Change these equations from slope/intercept form to standard form
Change these equations from slope/intercept form to standard form. y = 3x – 8 3x – y = 8 y = - ⅔ x + 7 2x + 3y = 21 y = ⅗ x – 2 3x – 5y = 10
