Constant of proportionality | the constant value of the ratio of two proportional quantities x and y |

Direct variation | a relationship between two variables that is expressed by an equation where one variable is equal to a constant times another. |

Linear Equation | a equation where each term is a constant or the product of a constant. |

Point-slope form | 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 |

Slope-intercept form | the equation of a straight line in the form y = mx + b where m is the slope of the line and b is its y-intercept |
