Presentation Transcript

1. 5.3 Slope-intercept form Identify slope and y-intercept of the graph & graph an equation in slope- intercept form. day 1

2. Linear equation: An equation that models a linear function. 1. The y-coordinate of a point where the graph crosses the y-axis. 2. where x= 0 y-intercept: Find the y-intercept: (0,2) or 2 y-intercept: y-intercept: (0, -3) or -3 y-intercept: (0,0) or 0

3. Slope-intercept form of a linear equation: y = mx + b slope y-intercept Identify the slope and y-intercept. y = -2x + 3 y = 6x y = mx + b y =6x+ 0 y = 5 y = mx + b y = 0x + 5 6 0 m = y-int or b = 0 5 m = y-int or b = -2 3 m = y-int or b =

4. Write an equation in slope-intercept form given the slope (m) and y-intercept (b). m = 2 b = 7 m = 2 b = -3 3 y = mx + b y = mx + b 2 3 x + 7 y = 2x - 3 ? =

5. Write an equation given the graph of a line. y = mx + b 1. Find 2 points on the line 2. Identify: 3 4 m = 1 b = 3. Write your equation: y = mx + b 3 4x + 1 ? =

6. Write an equation given the graph of a line. y = mx + b 1. Find 2 points on the line 2. identify: 2 1 -1 = -2 m = b = 3. Write your equation: y = mx + b ? = 2x - 1

7. Assignment: page 312: 7-21, 63-64,66, and 74-77 For 7-15: use m = for slope and b = for y- intercept 7) y = 3x + 1; m = b =
