    To find the inverse of an equation simply switch the X and y coordinates and solve for the new Y coordinate.

    Y = 2x + 4

    X = 2y + 4

    X - 4 = 2y

    X-4/2 = 2y/2

    Y = X - 4/2.

    The inverse is an equation that shows 'x' in terms of 'y'.

    The new equation will say

    x = something.

    We just have to take the given equation and solve it for 'x'.

    y = 2x + 4

    Subtract 4

    from each side: y - 4 = 2x

    Divide each side by 2 : (y-4) / 2 = x
