1 Write an equation in point-slope form for the line through the given point with the
given slope.
(10,-9); m --2
A y+9= -2(x - 10)
B y-9 = -2(x - 10)
C y - 10 = -2(x+9)
D y - 9 = -2(x + 10)

Answer:

A. y + 9 = -2(x - 10)

Step-by-step explanation:

The point-slope form of an equation of a line:

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

m - slope

(x₁, y₁) - point on a line

We have the slope m = -2, and the point (10, -9).

Substitute:

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