1. Find slope and y-intercept given an equation in standard form. 5.5 day 2 3x - 6y = 12

2. How?: Solve for y! 3x + 5y = 15 5y = –3x + 15 555 y = –3x + 3 5 Change from standard form to slope-intercept form. 3x + 5y = 15 -3x 3x - 6y = 12 -3x -6y = -3x + 12 - 6 y = -3x - 2 - 6 y = 1x - 2 2

3. Write an equation in slope-intercept form then find the slope and y-intercept. 8x + 4y = 12 Slope-intercept form: y = mx + b 8x + 4y = 12 -8x - 8x 4y = -8x + 12 444 y = -2x + 3 Slope =y-intercept = Slope-intercept form: y = mx + b y = -2x + 3 -2 Slope-intercept form: y = mx + b y = -2x + 3 3

4. 3x + 5y = 10 Slope-intercept form: y = mx + b 3x + 5y = 10 -3x - 3x 5y = -3x + 10 555 y = (-3/5)x + 2 Slope =y-intercept = Slope-intercept form: y = mx + b y = (-3/5)x + 2 -3 Slope-intercept form: y = mx + b y = (-3/5)x + 2 2 5 Write an equation in slope-intercept form then find the slope and y-intercept.

5. Write an equation in slope-intercept form, then find the slope and y-intercept. 4x + 2y = 8 Slope-intercept form: y = mx + b 4x + 2y = 8 -4x - 4x 2y = -4x + 8 222 y = -2x + 4 Slope =y-intercept = y = -2x + 4 -2 y = -2x + 4 4 4x + 2y – 8 = 0

6. Write an equation in slope-intercept form, then find the slope and y-intercept. 3x + 2y = 6 Slope-intercept form: y = mx + b -3x 3x + 2y = 6 2y = 6 – 3x 222 y = 3 – 3x 2 Slope =y-intercept = -3 2 3 y = 3 – 3x Slope-intercept form: y = mx + b 2 y = 3 – 3x Slope-intercept form: y = mx + b

7. I can find the slope and y- intercept given an equation in standard form. Assignment: worksheet: 5.5 day 2
