PreAlgebraC1/C2/C3
| Term | Definition |
|---|---|
| Like terms | Terms of an expression which have the same variables raised to the same exponent. |
| Simplest form | Simplest form of an algebraic expression is one which has no like terms and no parenthesis |
| Linear expression | An algebraic expression in which the exponent of the variable is 1 |
| Literal equation | An equation that has two or more variables |
| Inequality | A mathematical sentence that compares expressions |
| Solution of inequaility | A value that makes the inequality true. |
| Solution set | The set of all numbers which make a mathematical statement true |
| Graph of an inequality | graph that shows all the solutions of the inequality on a number line |
| Linear equation | An equation whose graph is a line |
| Solution of a linear equation | All of the points on a line that make the equation true |
| Slope | A ratio of the change in y (the rise) to the change in x (the run) between any two points on a line. It is a measure of the steepness of a line. |
| Rise | The change in y between any two points on a line |
| Run | The change in x between any two points on a line |
| X-intercept | The x-coordinate of the point where a line crosses the x-axis |
| Y-intercept | The y-coordinate of the point where a line crosses the 7-axis |
| Slope-intercept form | A linear equation written in the form y = mx + b. The slope of the line is m, and the y-intercept of the line is b. |
| Standard form | The standard form of a linear equation is a ax + by = c, where a and b are both not zero |
| Point-slope form | A linear equation written in the form y - y1 = m(x-x1). The line passes through the point (x1, y1) and the slope of the line is m |
