Verified Answer :

  1. we see that is has a yint of 1
    it has a slope of 2/3
    y=2/3x+1

    21. has a yint of -1
    has a sloe of -1
    y=-x-1

    22. from the center, go 3 units down and plot a point there
    from that point, go 4 units up, and 1 unit to the right, put a point there
    connect those 2 points wit a line

    23. go 2 units up from center
    go left and right forever (horizontal line going throug y=2 or (x,2)

    24. graph the point (1,-3)
    go 2 units up and  1 to right (-1,2) and plot a point, connect the points

    25. y=-1/4(x-10)
    graph the point (10,0)
    go 1 down and 4 to the right (14,-1) and connect the points
