2
Standard Form of a Line
Ax = By - C
x = 0
y = mx + b
Ax + By = C
3
Solution of a system of linear equations
y – y1 = m (x – x1)
its slope is undefinedor no slope.
Two or more linear equations containing the samevariables
ordered pair that makes all equationstrue (intersect point
4
Vertical Line
It has an undefined slope (or no slope).
Their slopes are opposite reciprocals.
Used to determine if a graph is a function
It has a slope of 0.
5
Perpendicular Lines
It is used to determine if a graph is a function.
Their slopes are equal.
A number. A term that has no variable.
Their slopes are opposite reciprocals.
6
Slope DEFINITION
A letter that represents one or more numbers.
y=mx+b
RISE/RUN
The point where a line(or curve) crosses the y – axis
