PreAlgebra C1/C2/C3
| Term | Definition |
|---|---|
| Like Terms | Terms of an expression which have the same variables raised to the same exponents |
| Simplest Form | The simplest form of algebraic expression is one which has mo like terms and no parentheses |
| 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 an Inequality | A value that makes the inequality true |
| Solution Set | The set of all numbers which make a mathematical statement true |
| Graph of an Inequality | A 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 y-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 is ax+by=c, where a and b are not both 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 |
