1. 8-6 Slope-Intercept Form
slope-intercept form - equation of the form y = mx + b, where m is slope and b is the y-intercept.
slope
y-intercept
over 1
y = mx + b
ex: y = 2x + 3
up 2
slope is 2
y-intercept is at (0,3)

2. Example State the slope and y-intercept. y = mx + b 1. y = 2x - 4
slope = y-int: -4
y = -7x + 9
slope = y-int: 9
y = x
slope = y-int: 0

3. Example Graph each equation using the slope and y-intercept.
Start at the y-intercept.
Plot the point!
Then plot the next point
using the slope.
