1. TODAY IN ALGEBRA…  Warm Up: Writing equation in slope- intercept form, then identifying the slope and y-intercept  Learning Goal: 4.6 You will write and graph direct variation equations.  Independent Practice

2. Identify the slope and y-intercept of the line with the given equation.

3. 4.6 DIRECT VARIATION : a linear equation shows direct variation when… the y-intercept is 0! With direct variation we call the slope: CONSTANT OF VARIATION

4. 4.6 DIRECT VARIATION: Writing in slope-intercept form to check for direct variation. EXAMPLE: Tell whether the equation represents direct variation. If so, identify the constant of variation.

5. 4.6 DIRECT VARIATION: Writing in slope-intercept form to check for direct variation. PRACTICE: Tell whether the equation represents direct variation. If so, identify the constant of variation.

9. 4.6 DIRECT VARIATION: Write and use direct variation
