Slope Intercept Form

slope y­intercept

Putting the equation in slope­intercept form is the same as solving for y.

­ the value of y when x = 0.­ where the line crosses the y­axis

y = mx + b 3 Graphing Lines SlopeIntercept  2016­17.notebook January 23, 2017

Graph using the Slope Intercept Method...

Graph the following lines:

1. m= 1/2, Y­intercept: (0, ­3)

2. ­6x ­ 4y = 20

5. y = ­x

6. 4x ­ y = 16

3. Points: (3, 6) and (0, 4)

4. y = ­5/6 x + 3 3 Graphing Lines SlopeIntercept  2016­17.notebook January 23, 2017

Special cases...

y = 6

x = ­8

x = ­5

y = 4

y = ­3

x = 1 3 Graphing Lines SlopeIntercept  2016­17.notebook January 23, 2017Let's MIX IT UP...

y = 2x

x = 5

y = ­1/3x

y = x

x = ­2

y = 3
