Question

Write an equation of the line in point slope form, that passes through the two given points

Answer 1

Answer:

  y -15 = -3(x +2)

Step-by-step explanation:

The slope will be ...

  m = (y2 -y1)/(x2 -x1)

  m = (-18 -15)/(9 -(-2)) = -33/11 = -3

Point-slope form is ...

  y -y1 = m(x -x1) . . . . . line with slope m through point (x1, y1)

Using the first point, the equation is ...

  y -15 = -3(x +2)
