Answer :

Answer:

  y +7 = 3(x +4)

Step-by-step explanation:

You want the point-slope equation of the line with slope 3 through point (-4, -7).

Point-slope equation

The point-slope equation of a line with slope m through point (h, k) is ...

  y -k = m(x -h)

Application

For m=3 and (h, k) = (-4, -7), this is ...

  y -(-7) = 3(x -(-4)) . . . . . substitute for m, h, k

  y +7 = 3(x +4)
