1) A math sentence that shows two expressions are equal. 2) A letter that represents an unknown number. 3) A number that does not change. 4) The number multiplied by a variable. 5) A number, variable, or product of both in an expression. 6) A math phrase with numbers, variables, and operations (no = sign). 7) Replace a variable with a number. 8) The value that makes an equation true. 9) To find the value of the variable 10) Get the variable by itself on one side of the equation. 11) Opposite operations (ex: + and −; × and ÷) used to undo steps.The point where the graph crosses the x-axis (when y = 0). 12) Multiply a number outside parentheses to everything inside. 13) Add or subtract terms with the same variable and exponent. 14) Both sides of the equation have the same value. 15) Equation solved with one operation. 16) Equation solved with two operations. 17) Equation that takes several steps to solve. 18) An equation that is true for every value of the variable. 19) No value makes the equation true. 20) Any value works; the equation is always true 21) Plug in your solution to confirm it works. 22) The state of two things being equal; shown by the = sign. 23) An equation whose graph is a straight line. 24) A relationship where two values change at a constant rate and pass through (0,0). 25) A relationship that does not pass through (0,0) and/or does not have a constant rate. 26) The constant ratio between two values in a proportional relationship. 27) A rate compared to one unit (ex: miles per hour). 28) A comparison of two amounts. 29) The steepness of a line; rate of change. 30) A method to find slope using vertical change over horizontal change. 31) How one quantity changes compared to another. 32) The point where a line crosses the y-axis; starting value. 33) The value at the beginning (same as y-intercept for linear functions). 34) The point where a line crosses the x-axis. 35) A visual representation of data or an equation. 36) A pair of numbers (x, y) that show a point on a graph. 37) A grid formed by the x-axis and y-axis. 38) The point (0,0) where the axes meet.
