Answer:

[tex]y - 9 = \frac{-1}{4}(x+2)[/tex] which is option A

Explanation:

The general form of the linear equation in point-slope form is:

y - y₁ = m(x - x₁)

where:

m is the slope

(x₁ , y₁) is a point on the line

We are given that:

slope of the line = m = [tex]\frac{-1}{4}[/tex]

the point on the line = (x₁ , y₁) = (-2 , 9)

We now substitute with the givens in the general form to get the equation:

[tex]y - y_{1} = m(x-x_{1})\\\\ y-(9) = \frac{-1}{4}(x-(-2))\\  \\ y-9=\frac{-1}{4}(x+2)[/tex]

Hope this helps :)

Answer:

The answer is A.
