Algebra 1 Chapter 4

McDougal Littell

Coordinate Plane A plane formed by two real number lines that intersect at a right angle.
Ordered Pair A pair of numbers used to identify a point in a plane.
X-coordinate The first number in a ordered pair.
Y-coordinate The second number in a ordered pair.
X-axis The horizontal axis in a coordinate plane.
Y-axis The vertical axis in a coordinate plane.
Origin The point (0,0) in a coordinate plane at which horizontal axis intersects the vertical axis.
Quadrants One of four parts into which the axes divide a coordinate plane.
Graph of an ordered pair The point in the plane that corresponds to an ordered pair (x,y)
Scatter plot A graph of pairs of numbers that represent real-life situations. It is a way to analyze the relationship between two quantities.
Solution of an equation A number that, when substituted for the variable in an equation, results in a true statement.
Graph of an equation The set of all points (x,y) that are solutions of the equation.
X-intercept The x-coordinate of a point where a graph crrosses the x-axis.
Y-intercept The y-coordinate of a point where a graph crosses the y-axis.
Slope The number of units a nonvertical line rises or falls for each unit of horizontal change from left to right.
Rate of change A comparison of two different quantities that are changing.
Constant variation The constant in variation model.
Direct variation The relationship of two variables x and y if there is a nonzero number.
Slope-intercept form An expression that has no perfect square factor other than 1 in the radicand, no fractions in the radicand, and no radicals appearing in the denominator of a fraction.
Parallel Lines Two different lines in the same plane that do not intersect.
Relation Any set of ordered pairs (x,y)
Function Notation A way to name a function that is defined by an equation.
Graph of a function The set of all points (x,f,(x), where x is in the domain of the function.
