insert the a corresponding x and y coordinate:
y + 3 = -2 (x + 9)
Don't forget to change the signs depending on whether their positive or negative:
(3, -9) since 3 is positive but there is a minus in the formula it would be -3
since -9 is negative and in the equation there's a minus sign you would change it to positive. (negative times a negative equals a positive)
