pg. 497/1, 3-6, 10-12, 15, 16, 18, 19 (GRAPH
ALL FUNCTIONS)
Warm up:
What is the slope and y-intercept of
each function?
1) y = 5x + 9
2) y = 2x
3) y = x
4) y = 7

Slope-intercept Form
y = mx + b
m = slope
b = y-intercept
(the point at which the line
intersects the y-axis)
December 11, 2013
y = (1/4)x - 3
December 11, 2013
2y + 6 = 8x
December 11, 2013
y = -x + 5
