WGU D126 STUDY GUIDE
run - Answer -In math, the horizontal distance between two points.
solution set - Answer -Group of all values that satisfy a mathematical statement. Values
that satisfy an equation or inequality.
y-axis - Answer -The vertical line that passes through the origin on a coordinate plane.
coordinate plane - Answer -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 - Answer -Measures one quantity in relation to another quantity.
rise - Answer -In math, the vertical distance between two points.
proportion - Answer -A true statement in which two ratios are equal to each other.
horizontal line - Answer -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 - Answer -The y-coordinate of a point where a line intersects the y-axis.
x-axis - Answer -The horizontal line that passes through the origin on a coordinate
plane.
slope - Answer -The value that describes the direction and steepness of a line drawn
on the coordinate plane.
constant of proportionality - Answer -Constant value of two proportional quantities,
expressed as a ratio.
degree - Answer -The largest exponent in an expression.
origin - Answer -The point on a coordinate plane where the x-axis and y-axis intersect.
Typically, this point represents 0 on both axes.
inequalities - Answer -The relationship between two unequal expressions.
ordered pair - Answer -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 - Answer -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 - Answer -Incorporates inequality signs.
slope-intercept form - Answer -A common format for a linear equation. It is of the form y
= mx + b, where m is the slope of the line and b is the y-intercept.
decreasing - Answer -Describes a line when X- and Y-coordinates are both reducing in
value when moving from the left to the right on a graph. This is associated with a
negative slope.
coordinates - Answer -Identifies the location of the point in relation to axes on a graph.
The x- and y-value of a point.
number line - Answer -A line in which points are matched to real numbers. The
numbers increase in value as you move to the right.
one-step equations - Answer -An equation that only requires one inverse operation to
solve.
like term - Answer -A term that has the same variable(s) with the same exponent(s) as
another term. The term can be combined with another like term using addition or
subtraction.
integer - Answer -A number (positive, negative, or zero) that can be represented
without a fractional or a decimal component.
parentheses - Answer -In mathematics, these symbols are used to separate operations
within an expression. Any operations that lie within these symbols should be performed
first. These symbols are also used to denote multiplication when a number or variable
lies directly outside of them.
quotient - Answer -The result of division.
arithmetic expression - Answer -A set of numbers connected by operations.
perimeter - Answer -The sum of the lengths of the sides of a two-dimensional figure.
base number - Answer -The number multiplied by itself when paired with an exponent.
For example, in 83, 8 would be the base number.
equation - Answer -Two mathematical expressions separated by the equals sign, =.
The two expressions on either side of the equals sign hold the same value as one
another.
