    if you arrange it like y=2x-5 than you can read off the slope. It is the multiplier of x, so it is 2. For the y-intercept, you have to set y=0 and than 2x-0=5 so x=5/2

    -2/-1 = slope = 2 yint = x=0; -5

    the slope is; ax+by = c -a/b

    y = (-a/b)x +c slope = -a/b

    depends on which form of the equation you want to write

    ax +by - c = 0 ax + by = c y = -(a/b)x + c y-y1 = (-a/b)(x-x1)

    what value is y when the graph is caught by the y axis ? the y axis is the x=0 axis what is the value of the equation when x=0?
