| Term | Definition |
|---|---|
| like term | terms of expression which have the same varibles raised to the same exponents |
| simplest form | The simplest form of algebraic exprssion is one which has no like terms and no parentheses. |
| linear expression | an algebraic exprssion in which the exponets of the variables is 1 |
| literal equation | an equation that has two or more varibles. |
| inequality | mathematical sentence that compares expressions |
| solution set | The set of all all numbers which make mathematical statement true. |
| graph of an inequality | A graph that shows all the solutions of the inequality of a number line. |
| linear equation | An equation graph is a line. |
| solution of linear equation | All the points on the 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 meassure of the steepness of a line. |
| rise | the change in y between any two points a line |
| run | the change in x between any two points 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 | a linear equation wriiten 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 ax+by=c, where a and b are not both zero. |
| points-slope form | Linear equation in the form y-y1(x-x1). The line passes through the point(x1,y1),and the slope of the line is m. |
