### 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
