- 1What is a dependent variable?A dependent variable is the Y coordinate, the value of Y depends of X. It usually represents the total in a term or stage.
- 2What is the independent variable?The independent variable is the X coordinate, the value of X does not depend on another variable. It usually represents the term or stage number.
- 3What is a numerical coefficient?The number that is multiplied by a value.
- 4What are algebra tiles? How are they used?Algebra tiles are tiles used to solve an algebraic equation such as 8 = -6 - (-2 x ). A variable tile is a tile that represents the unknown, x.
- 5How do you solve an equation with algebra?We need to isolate the variable on one side of the equation. To do this, we get rid of the numbers on that side of the equation. Whatever you do to one side though, you must do to the other.
- 6How do you solve an equation using fractions?You solve it by taking the unknown value, in this case "c", and dividing it by the independent variable. (in fraction form, put "c" over the independent variable.) You take the dependent variable and place it on the other side of the equal sign. From there multiply both sides by the divisor, or bottom half of the fraction, to get what "c" is equal to.
