    graph is linear:

    y=2x-4

    solve for x=o

    y=2x0-4 Eliminate 0

    y=-4 solved for y

    solve for y=0

    0=2x-4 add 4

    +4 + 4

    4=2x divide by 2

    /2 / 2

    4/2 = x

    2=x solved for x

    calculate the slope

    Solve for x=1

    y=2x1-4

    y=2-4

    y=2 solved for y

    Calculating the slope

    y - y

    a = x=1 x=0 = 2

    1

    The graph is

    (0, - 4) (2, 0)

    The domain is how far left and right it goes on a graph, and the range is how far up and down it goes on a graph. Because this equation is linear (if you graphed it, it would be in a straight line), both the domain and range are infinity, because it keeps going up and to the right, the larger X gets, and smaller and to the left, the more negative X gets.
