    need to work these out

    each of those functions form a line..
    for each function, solve the value of x when y=0. solve the value of y when x=0..
    plot the two points in the graph then connect them to form a line...

    I'm so confused
    on these 4 problems

  • 11th grade - , Thursday, September 16, 2010 at 9:08pm

    for example in #1.
    2x-1=y
    if y=0; 2x-1=0 then x=1/2
    if x=0; 2(0)-1=y then y=-1

    on the graph plot the points (1/2,0) and (0,-1)
    draw a line containing those points..
