Can someone finish this fast
dybincka [34]

Answer:

y + 9 = - 2(x - 9)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (9, - 9) and (x₂, y₂ ) = (- 2, 13)

m = \frac{13+9}{-2-9} = \frac{22}{-11} = - 2

Using (a, b ) = (9, - 9 ) , then

y - (- 9) = - 2(x - 9) , that is

y + 9 = - 2(x - 9)
