Answer:
y +1 = -5(x -4)
Step-by-step explanation:
You want the point-slope equation of the line with slope -5 through point (4, -1).
Point-slope equation
The point-slope equation of a line has the form ...
y -k = m(x -h) . . . . . . . line with slope m through point (h, k)
Application
Substituting m=-5 and (h, k) = (4, -1), the equation is ...
y -(-1) = -5(x -4) . . . . . . values substituted
y +1 = -5(x -4) . . . . . . . simplified a bit
