What is the equation of the following line written in slope-intercept form

The generic equation of the line is given by:
 y-yo = m (x-xo)
 Where,
 m = (y2-y1) / (x2-x1)
 m = (3 - (- 4)) / (- 2 - (- 1))
 m = (3 + 4) / (- 2 + 1)
 m = (7) / (- 1)
 m = -7
 We choose an ordered pair:
 (xo, yo) = (-1, -4)
 Substituting values:
 y - (- 4) = - 7 (x - (- 1))
 Rewriting:
 y + 4 = -7 (x + 1)
 y = -7x-7-4
 y = -7x-11
 
 y = -7x-11
