Match the word with the definition.

• A statement that two quantities are not equal. The symbols >, <, ≥, and ≤ are used to express inequalities.

• The value or values of the variables that make an equation true.

• A value that depends on another variable. The y value.

• The point where a graph crosses the x-axis.

Match the word with the definition.

• The number used to multiply a variable.

• Expressions that represent the same quantity.

• he number that expresses the steepness of a line. The slope is the ratio of the vertical change to the horizontal change between any two points on the line. Sometimes this ratio is referred to as the rise over the run.

• A variable that determines the value of another variable. The x value.
