Mario's dog has three puppies: Archie, Bailey, and Coco. Mario measures the weight of the puppies across several months. Then he represents their weight as a function of time. In all three functions, represents each puppy's weight in pounds and x represents the time in months.

---- Archie

--- Bailey

--- Coco

Step-by-step explanation:

Given

See attachment for the representation

Required

Determine the function (i.e. equation) of each

Archie

Take 2 point from the line of the graph

Calculate slope (m)

Archie's equation is:

Bailey

--- Given

Coco

Take 2 point from the table

Calculate slope (m)

Coco's equation is:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
