Answer :

Answer:

[tex] y-b= m (x-a)[/tex]

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:

[tex] a=4, b=-9[/tex]

And replacing we got:

[tex] y-(-9) =-4(x-4)[/tex]

[tex] y+9 =-4(x-4)[/tex]

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:

[tex] y-b= m (x-a)[/tex]

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:

[tex] a=4, b=-9[/tex]

And replacing we got:

[tex] y-(-9) =-4(x-4)[/tex]

[tex] y+9 =-4(x-4)[/tex]

And the best solution would be:

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