Algebra 1 - Unit 6/Lesson 2 Graphs of Linear Equations [y = mx + b] Slope: (\frac{\text{rise}}{\text{run}}) y-intercept: (0, b) Find the slope and y-intercept. (y = \frac{1}{4}x - 6) Slope = (\frac{1}{4}) y-intercept = (0, -6) (y = -3x + 0) Slope = -3 y-intercept = (0, 0) Find the equation of the line. slope = 6, y-intercept = -4 (y = 6x - 4) slope = (-\frac{1}{2}), y-intercept = 1 (y = -\frac{1}{2}x + 1) Graphing Vertical and Horizontal Lines Graph (x = 4) Vertical line Graph (y = -3) Horizontal line Example 1: Equation: (y = 3x + 1) Slope: (m = \frac{3}{1}) Y-intercept: (0, 1) Example 2: Equation: (y = -2x - 5) Slope: (m = -\frac{2}{1}) Y-intercept: (0, -5) Example 3: Equation: (y = \frac{1}{2}x + 3) Slope: (m = \frac{1}{2}) Y-intercept: (0, 3) Example 4: Equation: (y = -\frac{2}{3}x + 0) Slope: (m = -\frac{2}{3}) Y-intercept: (0, 0)
