    Equation of a line is y=mx+c
    m is the gradient and c is the y intercept

    gradient = change in y / change in x
    so it would be -7-5 divided by 6 – -6 = -12/12 = -1

    the equation is now y = -x+c

    now to find the y intercept you substitute one of the given coordinates into the equation we already have
    (6,-7) —> -7= -(-7) + c
    = -7 = 7 + c
    = c = -14

    we put that back into the equation to get line
    y = -x – 14
