run - correct answer ✔✔In math, the horizontal distance between two points.
solution set - correct answer ✔✔Group of all values that satisfy a mathematical statement.
Values that satisfy an equation or inequality.
y-axis - correct answer ✔✔The vertical line that passes through the origin on a coordinate
plane.
coordinate plane - correct 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 - correct answer ✔✔Measures one quantity in relation to another quantity.
rise - correct answer ✔✔In math, the vertical distance between two points.
proportion - correct answer ✔✔A true statement in which two ratios are equal to each other.
horizontal line - correct 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 - correct answer ✔✔The y-coordinate of a point where a line intersects the y-axis.
x-axis - correct answer ✔✔The horizontal line that passes through the origin on a coordinate
plane.
, slope - correct answer ✔✔The value that describes the direction and steepness of a line drawn
on the coordinate plane.
constant of proportionality - correct answer ✔✔Constant value of two proportional quantities,
expressed as a ratio.
degree - correct answer ✔✔The largest exponent in an expression.
origin - correct answer ✔✔The point on a coordinate plane where the x-axis and y-axis
intersect. Typically, this point represents 0 on both axes.
inequalities - correct answer ✔✔The relationship between two unequal expressions.
ordered pair - correct 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 - correct 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 - correct answer ✔✔Incorporates inequality signs.
slope-intercept form - correct 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 - correct 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.
