Answer:

3rd option

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 ) = (- 4, - 1 ) and (x₂, y₂ ) = (5, 7 )

m =
(7-(-1))/(5-(-4)) =
(7+1)/(5+4) =
(8)/(9)

using (a, b ) = (- 4, - 1 ) then

y - (- 1) =
(8)/(9) (x - (- 4) ) , that is

y + 1 =
(8)/(9) (x + 4)
