    x intercept is x=3

    y intercept is y=-3

    Step-by-step explanation:

    We can write this equation in a simpler way to find the values needed. Lets do it. Take:

    x-y=3

    And sum y in both sides, as we know the equality will maintain:

    x-y+y=3+y

    x = 3 + y

    Now subtract 3 in both sides:

    x-3 = y+3-3

    x-3=y

    So, we can rewrite our equation as y=x-3

    The x intercept is a value of x such that the equation in equal to zero; in other words, is the value of x when y is zero. It is also called a zero root. Graphically, its the x value when the function passes trough the x-axis. Lets find if, we nned that:

    x-3 = 0

    If we sum 3 in both sides:

    x-3+3=3

    x=3

    So, x=3 is x intercept

    For finding the y intercept we need the value of y when x is zero. Graphically, is the value of y obtained when the function passes trough the y-axis. So, replace x with 0:

    0-3=y

    y=-3

    Another way to get it is knowing that the y intercept in a polynomial is always the independent term, the one that has no x or y, which in this case is - 3.
