| Question | Answer |
|---|---|
| Slope-Intercept form | The form y = mx + b is the slope-intercept form of an equation for a line. |
| The y-intercept | The y-intercept b, is the value of y when x is 0 and it corresponds to the initial value of the dependent variable. |
| Standard form | When A and B are not both zero, the equation Ax + By = C is called the standard form of an equation for a line. |
| The x-intercept | The x-intercept is the value of x at the point where a graph crosses the x-axis. |
| Point Slope Theorem | If a line contains (x1, y2) and has slope m, then it has equation y - y1 = m(x - x1). |
| |x| Greatest Integer Symbol | |x| = the greatest integer less than or equal to x. ex: |5.65| = 5 |
| Arithmetic Sequence | A sequence with a constant difference between successive terms is called an arithmetic sequence. ex: 1,000, 4,000, 7,000, 10,000, 13,000 has a constant difference of 3,000 |
| Linear Combination | A combined equation Ex: 20P = 32L is a linear combination of P and L |
