quadrants - ANSWER-The four sections of the coordinate plane, separated and defined by the x-axis and y-axis. degree - ANSWER-The largest exponent in an expression. multiplication principle of equality - ANSWER-If both sides of an equation are multiplied by the same number, the result is an equivalent equation. cubic - ANSWER-An expression or equation of degree 3. variable - ANSWER-A symbol that represents a mathematical value. inverse operations - ANSWER-Two operations that undo one another. elementary operation - ANSWER-Addition, subtraction, multiplication, and division. arithmetic expression - ANSWER-A string of numbers connected by elementary operations. The Butterfly Method - ANSWER-Cross-multiplication method. The numerator of one fraction is multiplied by the denominator of the opposite fraction on both sides. linear - ANSWER-An expression or equation of degree 1. coefficients - ANSWER-A number by which a variable is multiplied. This number is written in front of the variable(s). y-intercept - ANSWER-The y-value of the point at which a line intersects with the y-axis. operation - ANSWER-A procedure which generates a new value from one or more operands, or mathematical values. slope-intercept form - ANSWER-A common format that a linear equation can take that is helpful for graphing purposes. It is of the form y = mx + b, where m is the slope of the line and b is the y-intercept.
