| Term | Definition |
|---|---|
| slope | the steepness of a line |
| Constant of Proportionality | the constant value of the ratio of two proportional quantities x and y |
| Direct Variation | mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other |
| X- intercept | the x-coordinate of a point where a line, curve, or surface intersects the x-axis |
| Y- intercept | the y-coordinate of a point where a line, curve, or surface intersects the y-axis |
| Linear equation | an equation between two variables that gives a straight line when plotted on a graph |
| Unit rate | the ratio of two measurements in which the second term is 1 |
| Rate of change | The ratio of the change in the output value and change in the input value of a function is called as Rate of Change |
| Slope-intercept form | an algebraic equation in which each term is either a constant or the product of a constant and a single variable |
| Proportional relationship | a relationship between inputs to outputs in which the ratio of inputs and outputs is always the same |
| Point-slope | the equation of a straight line in the form y − y1 = m(x − x1) where m is the slope of the line and (x1, y1) are the coordinates of a given point on the line |
| Intersecting lines | Lines that have one and only one point in common are known as intersecting lines |
