Answer:C

Step-by-step explanation:original formula is: y – y1 = m (x – x1) ordinates= (x1, y1)

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)
