  2. Section 6 – 2 Slope – Intercept Form Objectives: To write equations in slope-intercept form To graph linear equations

  3. Linear Equation: An equation whose graph is a line. Examples: y = 2x + 5 f(x) =

  4. y-intercept: the y-coordinate of the point where the line crosses the y-axis.

  5. Slope-Intercept Form of a Linear Equation: y = mx + b Slope-Intercept has TWO important parts: SLOPE: Y-INTERCEPT: y = 2x + 5

  6. Example 1 Identifying Slope & y-intercept Identify the slope and y-intercept of each equation. • y = 3x – 5 • y = -2x + 1 • y =

  7. Example 2 Writing an Equation Write an equation of the line with the given slope and y-intercept. • Slope = , y-intercept = 6 • Slope = -3, y-intercept = 4 • Slope = y-intercept =

  8. When you know the y-intercept and slope of a line, you can write an equation of the line! WATCH

  9. Example 3 Writing an Equation from a Graph A) Write the equation of the line.

  10. B) Write the equation of the line.
