    Complete each ordered pair so that it satisfies the given
    equation.

    1---- y = 2x + 5: (8, ), (-1, ), ( ,-1)

    Use the given equations to find the missing coordinates in the
    following tables.
    2------
    y= -x+4
    X Y
    -2
    0
    2
    0
    -2

    3-------------Graph each equation. Plot at least five points for each equation.

    x - 2y = 6

    4--------------find the slope of each line.

    5---------------

    6---------------Graph the line with the given point and slope.

    The line through (-2, 5) with slope -1

    7---------------
    Draw l1 through (-4, 0) and (0, 6). What is the slope of any
    line parallel to l1? Draw l2 through the origin and parallel to l1.

    8-----------------Write an equation for each line. Use slope-intercept form if
    possible.

    9------------

    10-------------Find the slope and y-intercept for each line that has a slope
    and y-intercept.

    X+2y=3

    11-----------
    Y+4x=8

    12----------determine whether the lines are parallel,
    perpendicular, or neither.

    Y=x+7
    Y=-x+2

    13------------Write each equation in slope-intercept form.
    Y+3=-3(x-6)

    14------------Find the equation of the line that goes through the given point
    and has the given slope.
    (-1, -5), -8

    15-------¬Find the equation of each line. Write each answer in slope intercept
    form.
    The line is parallel to -3x + 2y = 9 and contains the point
    (-2, 1).

    16------------Find the equation of each line in the form y = mx + b if
    possible.
    The line through (3, 2) with undefined slope

    17----------------Write a formula that expresses the relationship described by
    each statement. Use k for the constant in each case.
    m varies directly as p.

    18------------ Write a formula that expresses the relationship described by
    each statement. Use k for the constant in each case.

    u varies inversely as n.

    19-----------------Find the variation constant, and write a formula that expresses
    the indicated variation.
    c varies inversely as d, and c = 5 when d = 2.

    20-------------------- Solve each variation problem
    n varies directly as q, and n = 39 when q = 3. Find n
    when q = 8.
