run
In math, the horizontal distance between two points.
solution set
Group of all values that satisfy a mathematical statement. Values that satisfy an
equation or inequality.
y-axis
The vertical line that passes through the origin on a coordinate plane.
coordinate plane
A tool used for graphing that is a display of a two dimensional plane. It consists of an x-
axis and a y-axis; the x-axis being a horizontal number line, the y-axis is a vertical
number line, and the axes meet at the origin (0,0).
ratio
Measures one quantity in relation to another quantity.
rise
In math, the vertical distance between two points.
proportion
A true statement in which two ratios are equal to each other.
horizontal line
A line that runs left to right on the coordinate plane, parallel to the x-axis. It has no rise
or change in y-value.
y-intercept
The y-coordinate of a point where a line intersects the y-axis.
x-axis
The horizontal line that passes through the origin on a coordinate plane.
slope
The value that describes the direction and steepness of a line drawn on the coordinate
plane.
constant of proportionality
Constant value of two proportional quantities, expressed as a ratio.
degree
The largest exponent in an expression.
origin
The point on a coordinate plane where the x-axis and y-axis intersect. Typically, this
point represents 0 on both axes.
inequalities
The relationship between two unequal expressions.
ordered pair
Two numbers written in the form (x, y), where x represent the x-value or x-coordinate,
and y represents the y-value or y-coordinate.
increasing
Describes a line when X- and Y-coordinates are both gaining in value when moving
from the left to the right on a graph. This is associated with a positive slope.
linear inequality
Incorporates inequality signs.
