Slope-Intercept Form

Write the formula 5 times, as you write it say it aloud.

Identify the slope and y-intercept

y = 4x - 4

y = -2x + 5

m = b =

m = b =

Example: Find the slope of the line. Identify the y-intercept

3x - 5y = 5

YOU DO: Find the slope of the line. Identify the y-intercept

3x - 5y = 10
