WGU D126 Latest Update with Verified Solutions 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. coordinates Identifies the location of the point in relation to axes on a graph. The x- and y- value of a point. number line A line in which points are matched to real numbers. The numbers increase in value as you move to the right. one-step equations An equation that only requires one inverse operation to solve. like term 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 A number (positive, negative, or zero) that can be represented without a fractional or a decimal component. parentheses 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 The result of division. arithmetic expression A set of numbers connected by operations. perimeter The sum of the lengths of the sides of a two-dimensional figure. base number The number multiplied by itself when paired with an exponent. For example, in 83, 8 would be the base number. equation 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. factor An integer that evenly divides another integer. independent variable The variable that may be the cause of some result, or is presented as variable that offers an explanation. Also called an explanatory variable. property of equality If you perform equivalent operations to both sides of an equation, the result will always be an equivalent equation. dependent variable What is measured in an experiment. Also called a response variable, this is what is influenced as a result of an independent variable. greatest common factor (GCF) The greatest number that divides evenly into a given set of numbers. coefficient A number by which a variable is being multiplied. factoring In algebra, breaking an expression into its factors. These factors can be multiplied together, producing the original expression. unlike term A term that does not have the same variable(s) with the same exponent(s) as another term. The terms cannot be combined using addition or subtraction. algebraic expression A string of terms that are connected by division, addition, and subtraction operations. A string of terms that are connected by division, addition, and subtraction operations. product The result of multiplying. inverse operation An operation that undoes another operation. order of operations A set of rules that defines the order in which mathematical operations should be performed. equal sign The symbol '=.' Used in an equality to indicate that the expressions on either side of the symbol are equal to each other, or have the same values. distance formula Distance equals rate multiplied by time. degree The largest exponent in an expression. combine like terms Combining terms that have the same variable component. Combining like terms helps to consolidate when solving an equation. variable A symbol, such as x, that represents an amount or quantity that can change value. value A number or numerical worth.
