WGU D126 EXAM WITH CORRECT
ANSWERS { GUARANTEED A+}
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.
slope-intercept form - ✔✔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 - ✔✔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.
