| Question | |
|---|---|
| (x,y) table | two-column chart used to list pairs of related numbers, where the first column contains input values (x) and the second column contains output values (y) |
| pattern | a predictable sequence of numbers, shapes, or objects that follow a specific rule |
| graph | visual representations of mathematical relationships |
| rule | to find the rule of a function by identifying the pattern or relationship between the input values (x) and the output values (y) |
| equation | a mathematical sentence that shows two things are equal by using an equal sign |
| shift | move the graph of a function up, down, left, or right without changing its basic shape or orientation |
| x-value | a variable that represents an unknown input number x in (x,y) and known as the independent variable |
| y-value | a variable that represents an unknown output number ( y ) in (x,y) and known as the dependent variable |
| y=mx+b | slope intercept form where slope is (m) and the y-intercept is (b) |
| x-axis | the horizontal number line on a coordinate plane |
| y-axis | the vertical number line on a coordinate plane |
| growth rate | measures how much a specific variable changes over a designated period, expressed as a percentage of its starting value |
| x-intercept | the point where a graph crosses the horizontal x-axis, and it always has a y-value of zero ( ? , 0) |
| y-intercept | the point where a line or graph crosses the vertical y-axis, and it always has a x-value of zero (0 , ?) |
| starting value | it is the value of y when x = 0 |
| variable | a symbol—usually a letter like x, y, or n—that acts as a placeholder for a number whose value is unknown or can change |
| coefficient | a number that multiplies a variable in an algebraic expression |
| growth triangle | right triangle drawn on a graph to find the slope of a line |
| trend line | a straight or curved line drawn on a graph or chart to show the general direction and pattern of data over time |
| point of intersection | the exact location where two lines, curves, or axes cross each other on a graph |
| solution | a value, or a set of values, that makes an equation, inequality, or system true when you substitute it for the unknown variable |
| steepness | measures how sharply a line or curve goes up or down on a graph |
