Scribe Post for April 29, 2010

Hey everyone! On Thursday April 29, we learned about the term "Slope."

m = slope

y =[mx] + [b] y intercept
slope ^

Slope formula:
y2 - y1 = m
x2 - x1

Ex. (0.1, o.023)
(0.4, 0.092)

y2 - y1 = 0.092 - 0.023
x2 - x1 0.4 - 0.1

= 0.069
0.3

= 0.23

y intercept formula:
y - y1 = m (x-x)

Ex. (0.1, 0.023) (0.4, 0.092)
(x1, y1) (x2, y2)

y - y1 = m (x-x)
y - 0.023 = 0.23 (x-0.1)
y - 0.023 = 0.23x -0.023
y = 0.23x - 0.023 + 0.023
y = 0.23x
