Tricky Slopes and y-Intercepts - 14:34
KEY CONCEPTS:
In order to use the slope and intercept rules, equation MUST be in the form of y=mx+b
TRICKS to be Careful of:
y=4 (horizontal line - therefore slope is 0)
x=4 (vertical line - therefore slope is undefined)

Slope y-Intercept Form - 20:48
KEY CONCEPTS:
Slope/y-Intercept form is: y=mx+b
m=slope (value in front of x ONLY when in this form y=mx+b)
b=y-intercept
slope=rise/run
