    Solve the given equation for y to obtain the slope and y-intercept of this equation:

    -3x + 9y = 18

    Add 3x to both sides: 3x - 3x + 9y = 18 + 3x

    Simplifying, 9y = 3x + 18

    Dividing both sides by 9 to solve for y:

    y = (3/9) x + 2 or (after reduction) y = (1/3) x + 2

    The slope is 1/3 and the y-int. is (0,2).
