    Step-by-step explanation:

    If we know the slope and the y intercept, we can use the slope intercept form to write the equation

    y = mx+b where m is the slope and b is the y intercept

    y = - 3x + 3

    We want to find the x intercept

    Set y = 0 and solve for x

    0 = - 3x+3

    Subtract 3 from each side

    -3 = - 3x

    Divide each side by - 3

    -3/-3 = - 3x/-3

    1 = x

    The x intercept is 1
