    The answer to your question is 1

    Step-by-step explanation:

    Data

    slope = m = - 3

    y-intercept = 3

    Process

    1. - Find the equation of the line in the slope-y-intercept form

    y = mx + b

    -Substitution

    y = - 3x + 3

    2. - Find the x intercept

    -If y = 0

    0 = - 3x + 3

    -3 = - 3x

    -3/-3 = x

    x = 1

    -The x-intercept is 1
