TermDefinition
absolute value function A function of the form f(x) = l mx +b l + c, where m not equal to 0.
dependent variable In the order pair (x,y), y is this type of variable because y depends
domain In a relation is the set of all inputs, or x-coordinates of the ordered pairs
translation Shifts the graph horizontally, vertically, or both. It results in a graph of the same shape and size but possibly in a different position.
standard form A linear equation in the form of Ax + By = C, where A B, and C are real numbers, and A and B are not both Zero.
x-intercept Is where the line crosses the x-axis
slope-intercept form If the form of a line written as y = mx + b
slope Is the ratio of the vertical change to a corresponding horizontal change.
vertical line test Is used to determine whether the relation is a function when looking at a graph.
point-slope form Is the form of a line written as y-y1 = m(x - x1)
linear inequality In two variables it has a graph in which the boundary line separates the shaded region from the un-shaded region.
function Is a relation in which each element of the domain is paired with exactly one element in the range.
perpendicular lines The lines have opposite reciprocal slopes
parallel lines The lines have the same slope but different y-intercepts
relation Is a set of pairs of input and output values and is written as a set of ordered pairs
y-intercept Is where the line crosses the y-axis
range is the set of all the outputs, or y-coordinates of the ordered pairs
linear equation Is an equation that can be written in the form y = mx + b or y=y1 = m(x-x1) or Ax + By = C
