  • a _ is a set of ordered pairs

    relation

  • the graph of every linear in two variables in a _

    line

  • The statement \(-x+2y > 0\) is called a(n _ in two variables

    linear inequality

  • form of a linear equation in two variables is \(Ax+By=C\).

    standard

  • The _ of a relation is the set of all second components of the ordered pairs of the relation.

    range

  • lines have the same slope and different \(y\)-intercepts.

    parallel

  • form of a linear equation in two variables is \(y=mx+b\).

    slope intercept

    • A(n) is a relation in which each first component in the ordered pairs corresponds to exactly one second component.

    function

    • In the equation \(y=2x-4\), the coefficient of \(x\) is the _ of its corresponding graph.

    slope

  • Two lines are _ if the product of their slopes is \(-1\).

    perpendicular

  • To find the \(x\)-intercept of a linear equation, let _= \(0\) and solve for the other variable.

    y=0

  • The _of a relation is the set of all first components of the ordered pairs of the relation.

    domain

  • A(n)_ is a function that can be written in the form \(f(x)=mx+b\).

    linear function

    • To find the \(y\)-intercept of a linear equation, let _ \(0\) and solve for the other variable.

    x=0

  • the equation \(y-5 = -1(x+8)\) is written in _ form

    point-slope form
