constant of proportionality | the constant value of the ratio of two proportional quantities x and y; usually written y = kx, where k is the factor of proportionality |
direct variation | algebra/ao4/ldirect.htm When two variable quantities have a constant (unchanged) ratio, their relationship is |
linear equation | an equation between two variables that gives a straight line when plotted on a graph. |
point-slope form | The "point-slope" form of the equation of a straight line is: y - y1 = m(x - x1) ... one point on the line; and the slope of the line,. you can find other points on the line. |
slope-intercept form | A linear equation is an algebraic equation in which each term is either a constant or the product of a constant and a single variable. Linear equations can have one or more variables. |
rate of change | Momentum and rate of change are simple technical analysis indicators showing the |
slope | a surface of which one end or side is at a higher level than another; a rising or falling surface. |
x-intercept | of a line is the point at which the line crosses the x axis |
y-intercept | The y-intercept of a line is the point at which the line crosses the y axis |
unit rate | The estimated market value contribution for each unit of an improvement |
proportional relationship | is a relationship between two quantities, usually represented by the equals sign " (=)". |
intersecting lines | The notion of line or straight line was introduced by ancient mathematicians to represent straight objects with negligible width and depth. Lines are an idealization of such objects |
