Question

Write an equation of a line in point-slope form that has a slope of -2 and passes through (5, -1).

Answer 1

Answer:

  A.  y + 1 = -2(x – 5)

Step-by-step explanation:

For a line with slope m through point (h, k), the equation is ...

  y -k = m(x -h)

Fill in your values of m=-2, h=5, k=-1 and you have ...

  y -(-1) = -2(x -5)

  y +1 = -2(x -5) . . . . . . simplify. Matches selection A.
