Vocabulary STAAR Practice 2 of 3
| Term | Definition |
|---|---|
| Dependent Variable | the output variable (y) whose value in a function is determined by the input variable (x) |
| Independent Variable | the input variable (x) whose value in a function affects the output variable (y) |
| Negative Slope | if the line goes down and to the right on a graph |
| Zero Slope | (y = #) is a horizontal line |
| Slope | A measure of steepness of a straight line defined as rise over run |
| Undefined Slope | (x = #) is a vertical line |
| y-intercept | where the line or parabola crosses the y-axis |
| Δx | indicates change in the domain |
| Δy | indicates change in the vertical axis |
| Line of Best Fit | a line drawn through or near data points that most accurately represents a set of data |
| Linear Function | Data sets that have a constant rate of change and form a straight line, have x as the input variable where x is raised only to the first power |
| Point-Slope Form | equations written as y-y1=m(x-x1) |
| Slope-Intercept Form | y = mx + b, where m= slope b = y intercept and (x , y) shows the coordinate of a point on the line |
| Standard Form | ax + by = c where a, b and c are integers |
| Infinitely Many Solutions | linear systems of equations that have an infinite number of solutions are the same line |
| No solution | when a system of equations do not have an intersection |
| System | equations that you solve at the same time |
