    The equation y = 2x-2 can be written as y = 2x + (-2)

    Adding a negative number is the same as subtraction. Eg: 2 + (-3) = 2-3

    The equation y = 2x + (-2) is in the form y = mx+b where

    m = 2 is the slope

    b = - 2 is the y intercept

    Therefore the final answer is simply - 2

    The graph crosses the y axis at - 2 on the vertical number line. The y intercept as an ordered pair is (0,-2). The x coordinate is always 0 for the y intercept.
