Answer
Circle
The set of all point in a plane that lie a fixed distance from a given point in the plane.
Linear Equation
Any equation in the form Ax + By = C. The graph of a linear equation is a line.
X-Intercept
The point where the graph crosses the x-axis.
Y-Intercept
The point where the graph crosses the y-axis
Zero of an equation
The solution to the equation
Root of an equation
The solution to the equation
Slope
A numeric meausre of the steepness of a line.A numeric meausre of the steepness of a line.
Point-Slope Form of an Equation
Y - y1 = m(x - x1) where m = slope of the line and (x1, y1) represent a point on the line
Slope-Intercept Form of an Equation
Y = mx + b where m = slope of the line and b represents the y-intercept of the line
Perpendicular lines
Two lines that intersect at a right angle. The slopes of perpendicular lines are opposite reciprocals of each other.
Parallel lines
Two lines that do not intersect. The slope of parallel lines are the same.
Function
A rule that assigns each element in one set to a unique element in a second set.
Vertical Line Test
A graph is the graph of a function if and only if there is no vertical line that crosses the graph more than once.
