1. Slope-Intercept Form

2. Warm-up: Find the slope of the following: Find the slope of the line passing through: (-1,- 2)(3,4) Slope = 6 4 Find the slope of the line passing through: (- 1,1)(4,3) Slope = 2 5 Find the slope of the line passing through: A(-2,1) B(6,7) Slope = 6 8

3. Slope-Intercept Form Linear Function: A function that graphs a line Linear Equations: Are equations that model a Linear Function

4. Y-intercept y-intercept is the y-coordinate of the point where a line crosses the y-axis Where is the y-intercept of this line? Y-intercept: (0,1)

5. Slope Intercept Form Slope intercept form of an equation: Y=mx+b SlopeY-intercept

6. Example: Y = mX + b 1. What are the slope and y-intercept of: y=3x-5 Slope: 3 Y-intercept: -5 2. Write an equation of a line with a slope of ¼ and y-intercept at 7 Y = mX + b Y = ¼X + 7
