### 6.2-3 Slope-Intercept and Standard forms

1. 1. Bellwork Solve for x Solve for y
2. 2. 1. IWBAT find slope and y-intercept using the slope-intercept form. 2. IWBAT write the equation of a line from given information.
3. 3. Slope-Intercept Form linear equation : y = 3/2x + 3, y = -5x - 2 (not all equations are linear) y-intercept : y-intercept : crosses the y axi s
4. 4. Slope-Intercept Form y-intercept, substitute, slope, y-intercept
5. 7. Bellwork y = mx + b 1. What does the &quot;m&quot; stand for? 2. What does the &quot;b&quot; stand for? 3. Solve for y. 3y = 2x + 6 4. Solve for y. Then find the slope and y- intercept. 5y = 7x - 10
6. 8. Write an equation of the line with slope 3/8 and y- intercept 6. Write an equation of the line with slope -3 and y- intercept 4.
7. 9. Writing an equation from a graph Step 1: Find slope. Step 2: Use slope- intercept form.
8. 10. Write the equation of the line.
9. 11. Bellwork Write the equation of the line. What is the slope and y-intercept of: y = mx + b
10. 12. 1. IWBAT graph linear equations using the slope-intercept form and standard form. 2. IWBAT transform linear equations from standard form to slope-intercept form.
11. 13. Graphing equations Graph y = 3x - 1 Graph y = 3/2x - 2
12. 14. 1. Solve for y, then graph the line. 3y = 4x - 6
13. 15. Using standard form Ax + By = C Find the &quot;x&quot; and &quot;y&quot; intercepts of 3x + 4y = 8. Graph the line.
14. 16. Find the x- and y- intercepts of 2x + 3y = 12. Graph the line.
15. 17. Find the x- and y- intercepts of 5x -- 3y = 15. Graph the line.
16. 19. Transforming to standard form Write y = 3/4x + 2 in standard form using integers. Multiply both sides by denominator using distributive property Distribute Move x term to the left side.
17. 20. Transform y = -2/5x + 1 into standard form. Transforming to standard form
18. 21. H/W: p. 294 # 22 - 36 even p. 301 # 1 - 33 every other odd
