Description
| Question | Answer |
| Absolute value | The absolute value of a number is the distance between the number and the origin (0). Ex: |-9| = 9 because -9 is 9 spaces away from 0 in the negative direction. |
| Adjacent angles | Two angles in a plane which share a common vertex and a common side but do not overlap. |
| Scientific notation | A standardized way of writing real numbers. All real numbers are written in the form a x 10^b, where 1 ≤ a < 10 and b is an integer. Ex: 351 is written 3.51 x 10^2 in scientific notation. |
| Median | The value for which half the numbers are larger and half are smaller. If there are two middle numbers, the median is the arithmetic mean of the two middle numbers. |
| Mean | Average |
| Mode | The number that occurs the most often in a list. |
| Midpoint | The point halfway between two given points. The midpoint formula is: ((x1+x2)/2, (y1+y2)/2) |
| X-intercept | A point at which a graph intersects the x-axis. Y=0 where the line crosses the x-axis, so plug 0 in for y and solve for x. |
| Y-intercept | A point at which a graph intersects the y-axis. |
| Slope | A number which is used to indicate the steepness of a line, as well as indicating whether the line is tilted uphill or downhill. Slope (m) = rise (y2-y1)/run (x2-x1). |
| Reciprocal | The reciprocal of x is 1/x. In other words, a reciprocal is a fraction flipped upside down. |
| Slope intercept form of an equation | Y = mx + b, where m is the slope and b is the y-intercept. |
