y - y₁ = m(x -x₁)

slope m = -2,  from point (10, -9) ,  x₁ = 10, y₁ = -9

 y - y₁ = m(x -x₁)

y - -9 = -2(x - 10)

y + 9 = -2(x - 10) 

Answer:

The required equation is [tex]y+9=-2(x-10)[/tex]

Step-by-step explanation:

To find : Write an equation in point-slope form for the line through the given point with the given slope. (10, -9); m = -2

Solution :

The slope formula of the equation of line is

[tex](y-y_1)=m(x-x_1)[/tex]

Where, m is the slope and [tex](x_1,y_1)[/tex] is the point.

According to question,

[tex](x_1,y_1)=(10,-9)[/tex]

The slope is m=-2

Substitute the value in the equation,

[tex](y-(-9))=(-2)(x-10)[/tex]

[tex](y+9)=-2(x-10)[/tex]

Therefore, The required equation is [tex]y+9=-2(x-10)[/tex]
