99/3=33
33*2=66

66 bottles in Tiffany's collection are made of crystal.

Write an equation of the line that passes through the points (1,-4) and (2,-1).
Anastaziya [24]

Answer:

  y = 3x -7

Step-by-step explanation:

The 2-point form of the equation of a line is useful for this.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (-1 -(-4))/(2 -1)(x -1) -4

  y = 3(x -1) -4

  y = 3x -7
