Linear Equations/Functions
The ratio of the rise, or vertical change, to the run, or horizontal change, between any two points on a nonvertical line on the coordinate plane.
Slope
Less than or equal to and Less than
Is shaded below the line
Two or more lines graphed at the same time
System of Equation
Where the graph turns
Vertex
A form of a linear equation, y=mx+b, where m is the slope and b is the y-intercept of the graph of the equation.
Slope-intercept form
Greater than or equal to and Greater than
Is shaded above the line
The point(s) that two lines share
Solution of a System
A line through a parabola so that each side is a mirror image.
Axis of Symmetry
The point on a coordinate plane where the graph of a line crosses the y axis
Y-intercept
Less than and Greater than
Dotted or Dash Line
Where the lines meet
Intersect
The vertex at the highest point
Maximum
Another word for zeroes, solutions, and roots.
X-intercept
Greater than or equal to and Less than or equal to
Solid line
In a system of linear equations this means the lines are parallel
No Solution
The vertex at the lowest point
Minimum
A function that is represented by a straight line
Linear Equation
It has multiple solutions/answers that can satisfy the equation
Solution Set
In a system of linear equations this means that the two lines lie on top of one another
Infinite Solution
A U shaped line on a graph
Parabola
