O A. y + 9 = -4(x-4)
O B. y - 9 = -4(x + 4)
O C. y+ 9 = 4(x-4)
O D. y - 9 = 4(x + 4)

For this case we know that m =-4 represent the slope. And with the point given (4,-9) we can find the values of a and b and we got:

And replacing we got:

And the best solution would be:

A. y + 9 = -4(x-4)

Step-by-step explanation:

For this case we need to remember that the general expression for the slope line is given by:

For this case we know that m =-4 represent the slope. And with the point given (4,-9) we can find the values of a and b and we got:

And replacing we got:

And the best solution would be:

A. y + 9 = -4(x-4)
